Android virus is a term used to describe a group of malicious applications targeting Android smartphones and tablets. Based on the analysis held in 2018, Xender, Amber Weather Widget, Touchpal, Kitty Play, Z Camera, ES file explorer are the apps that can be downloaded from Google Play Store, but trigger aggressive ads that lead to Android virus infection. The infected device might exhibit a lock screen or encrypted data or pop-up messages and intrusive commercial content. The other typical symptom is aggressive redirects, which may feature pornographic content, warn the potential victim about rogue virus infections or display hoax prize giveaways. The best example of such behavior is the notorious virus, that affected millions of machines in recent years.

These cyber threats have been spreading around since 2015, but it seems that they won't stop doing that in 2018. Two of the most widespread members of Android virus group showed up in November 2017. They are known as Matcher Trojan and Tizi spyware . The latter has initially been found in 2015 which has been around since 2015 and has been used to steal personal information from social media apps.

Among other recently discovered cyber threats, there is also DoubleLocker ransomware that emerged in October. It not only encrypts files on the targeted Android device but changes phone's PIN. What is more, malware might also steal money from victims bank or PayPal account.

Beware that Android malware can now bypass Google's security and pretend to be a useful app in the Play Store. That was revealed when one of its variants, LeakerLocker, was spotted spreading using this technique. Other versions, such as vGhostCtrl , can open the system"s backdoor and allow attackers to record victim"s audio/video files or steal important data.

In July 2017, researchers discovered a new version of Android malware known as “Invisible Man” which steals banking app data and other sensitive data. Thus, it only proves that Android users should pay attention to their devices" security.

In fact, almost all Android viruses are interested in getting personally identifiable information about the victim. Most often, this information includes credit card details, logins, and password s.

Other variants cause less damage, such as sharing a victim’s contact list, recording conversations, delivering unwanted pop-up ads, initiating redirects to various websites or infecting the device with other malware. According to cybersecurity research related to Android virus which has been held at the beginning of 2018, numerous apps distributed on the Google Play Store can be infected with intrusive ads, which can be used for spreading more severe infections. Xender, Amber Weather Widget, Kitty Play, Touchpal, Z Camera are just a few examples.

You should also be careful with ES file explorer app, which claims to be able to boost Android's battery life. Instead of being useful, this application may lock the screen and display disruptive Android ads that refuse to go away.

If you noticed that your tablet or phone is being oddly, you should not ignore these symptoms of the possible infection. If you have been dealing with slowdowns, suspicious alerts, redirects or received an increased telephone bill, you should check your device for malware because they are the main signs showing that you are infected. To remove Android virus, you can use the mobile version of .

Android virus reigns in 2017 and keeps evolving in 2018

Marcher Android Trojan, also known as ExoBot, is a banking malware that is known at least since 2013. Researchers reported about virus comeback in November 2017. The updated version of the malware included three hazardous components into one campaign: malware, credential phishing, and banking data theft. Security experts warn that this version of Android malware is more complicated and difficult.

Previously Marcher malware spread via SMS or MMS messages. However, crooks changed distribution method and sent a shortened link to a phishing via email in order to avoid detection. The recent campaign has been active at least since January 2017 and targeted customers of Austrian banks.

The malicious email includes a link to a fake Bank Austria website where users have to log in and enter their email address and phone number. Ten attackers send a victim a warning that he or she does not have the “Bank Austria Security App” installed on the phone and asks to download it from the provided link.

However, the installation of the malicious app requires altering security settings to download it from an unauthorized source. Malware requires lots of permissions that get attackers full access to the smartphone.

Once installed, a malicious app creates a legit-looking icon on the homes screen that looks similar to Bank Austria. After installing Marcher virus, victims are asked to enter their credit card information or other personally identifiable details whenever they open any applications.

According to the recent information, about 20,000 Android users may have suffered from this scam and installed ExoBot on their devices.

Google's security firewall can be easily bypassed by malicious Android apps

The most of the Android viruses can be downloaded from the Google Play store, together with safely-looking apps. No matter how much effort Google puts while trying to protect users and prevent these malicious apps from bypassing their security, viruses find a way to this store. Recently, security experts reported about a list of over 75 applications infected with Xavier Android virus found on the Google Play Store.

Recently, security experts reported about a list of over 75 applications infected with Xavier Android virus found on the Google Play Store.

However, it's not the only way how Android virus can infect the device. In February 2016, one of the variants was noticed spreading via text messages. Once inside the system, it enabled illegal connections.

In 2017, security experts reported about several variants of this malware using sophisticated social engineering techniques to infiltrate the device via trojanized apps. Therefore, you should be careful when installing third-party apps because they can be infected with the 10001_1.jar virus.

You can also get Rabbitfiles virus or similar malware from the third-party or file-sharing websites. Besides, Whatsapp ads and similar notifications can also result in problems related to your Android phone. It "s clear that 2017 means a new era for Android viruses. If in 2016, one in ten apps was infected, now this number continues growing.

Android virus is a deceptive software designed for Android operating system. There are many variants of the malware that targets smartphones, tablets and other devices running this OS. Typically, the virus locks the device and asks to pay money or call scammers for "help."

Symptoms of the Android virus

Getting infected with Android virus is surely a frustrating experience. Pushy ads signal that there's something wrong with your Android device. Security researchers highly recommend avoiding lottery-themed and similar ads that can start interrupting you once you start using your device.

Besides, you should pay attention to such signs as constant freezes on your device. If your phone or other Android-based device has started freezing up and stopping from functioning while you are browsing the Internet, you should install Android antivirus to check it.

Also, pay attention to your telephone bill and track the numbers. If you have started receiving increased telephone bill, you should double check your month's report. There is a high possibility that the infection has signed you up for some premium service. To save the money, you have to take care of Android virus removal on your device.

To prevent such threats, you should think about Android antivirus software. However, some experts claim that prevention of such malware does not require security apps because Android is safer than other operating systems, but they also agree that you need to think about prevention techniques to save yourself from such viruses.

Mobile viruses mostly spread via free third-party app stores

Android virus has been actively spread via third-party apps that have to be installed on the phone manually. However, new methods used for distributing this threat have started spreading around, and today you can get infected with this virus by clicking on the malicious link as well.

In most of the cases, people download this threat to their devices in a bundle with unlicensed or experimental apps that are actively promoted on the Google Play store and similar locations.

To avoid this, we highly recommend you to download your apps only from legitimate app stores that check every program before they start promoting it. Google Play Store, Amazon and Samsung can be trusted in this case. Besides, even if you select any of these app stores, you should still double check the app before downloading it to your device because you can never know what kind of malware is hiding in it.

If you are interested in cyber security, you must have already heard about hackers who managed to add their malicious app to the Google Play store and collected more than 10.000 downloads before it was revealed. Also, it has been reported about affected websites that can download an infected app to your phone automatically.

To keep your device clean and ensure protection against Android virus, you should stop visiting suspicious/illegal sites and never click links that may show up for you while visiting them. Finally, we believe that it is time to think about mobile antivirus that could help people prevent installation of malicious apps, including Android malware.

The list of infected Android apps (malware list)

JavaTcmdHelper virus is one of the applications that cause issues on Android phones and can often be detected as dangerous by antivirus programs.

This application doesn't show up on the phone or even in Settings or Application sections. However, users have reported about system messages stating that Javatcmdhelper is possibly dangerous. The message may also state about the app that behaves unusually or has privacy risks.

Java tcmd helper virus can be detected by your anti-malware tool or security app but the name depends on a particular virus database and may differ from program to program.

The most common heuristic name is Artemis!7123f6c80769 or Artemis!f580cadc3dc1. Because of this, it gets called Artemis/JavaTcmdHelper virus by various users.

To perform these commands, Android malware modifies the source code of the official Tesla app at first. Then, it shares victim"s username and password with the attackers and helps them steal the car. However, the virus, which was tested by Promon researchers, does not rely on any security vulnerabilities of the Tesla app. According to the company, it has to be installed manually with the help of social engineering and similar techniques.

However, the virus, which was tested by Promon researchers, does not rely on any security vulnerabilities of the Tesla app. According to the company, it has to be installed manually with the help of social engineering and similar techniques.

Unfortunately, getting rid of Ghost Push is almost impossible, even factory reset does not do the job, and reflashing firmware would be the only choice for users. However, the good news is that those who are using Nougat, Oreo, and Pie should feel relatively safe, as those versions of the Android OS are protected from this type of malware. Nevertheless, it does not mean that hackers will not create new variants that would defeat protections measures in the latest versions of Android.

gooligan malware has corrupted over 86 applications, such as Youtube Downloader, Kiss Browser, Memory booster, Demo, Perfect Cleaner, Battery Monitor, System Booster, etc. It seems that all system performance and browser-related programs and gaming, as well as pornographic applications, risk becoming the carriers of Gooligan. Over 74% of all Android phones might be vulnerable to this new version of the virus.

After the infection process is complete, the malware roots the device and enables full access to install more malicious elements. Such activity is done for the sole purpose of stealing your personal information such as login data to banking accounts.

Interestingly, which hit the stage last year, provided a foundation for the current malware. Needless to say, the improved version is much more treacherous.

This malicious virus is an updated copy of HummingBad malware which is known for its massive attacks against Android users. Back in 2016 , this virus managed to wreak havoc on approximately 10 million Android devices. Recently, HummingBad appeared in a new form and a new name, and this time it is dubbed HummingWhale malware.

HummingWhale malware was apparently available on the Google Play Store for a while in the form of 20 various applications, most of them being called Camera. Examples include Rainbow Camera, Whale Camera, Ice Camera, Hot Camera, and similar applications.

The malware used to set up a virtual machine on the infected device, stealthily install extra applications on the device and serve annoying advertisements for the user. Once the user closed an ad, the malware uploaded already installed shady program to the virtual machine to create a fake referrer ID, which is used to generate revenue.

. First discovered in February 2016, malware has already infected more than 10 million Android users. The malware had been spreading via “drive-by download attacks,” and users got infected after particular visiting malicious websites. In the January 2017, malware has been spotted actively spreading again on Google Play store as HummingWhale application.

After infiltration, HummingBad malware gets access to the core of the smartphone's operating system. Then, it starts delivering misleading ads and displaying alerts about necessary system updates. When users click on these advertisements, developers of the application generate revenue. However, it's not the main problem.

Malware also gets full access to the infected device and can steal users’ private information, such as contacts, logins, credit card or banking information. For this reason, it's crucial to remove HummingBad as soon as it shows up on the device.

Also known as Android.Lockdroid.E, malware spreads as a pornography app “Porn ‘O’ Mania”. The virus uses social engineering techniques to get admin rights of the infected device. It aims to achieve this goal by using fake package installation. As soon as the installation is completed, Lockdroid virus gets full access to the device and encrypts data.

What is more, it can change the PIN and lock the device. In this way, malware elimination might become difficult. Malware uses clickjacking technique and attacks smartphones and tablets with Android 5.0 or newer versions of the OS. According to the Google , this malicious app cannot be downloaded from the Google Play Store.

GhostCtrl virus exploits an Android vulnerability to help its owners to get control over the device. It showed up in the middle of 2017 when it was found attacking Israeli hospitals, but it is not considered a new virus. However, according to some of

However, according to some of the security experts, malware is not going to stop – soon it can become a ransomware-type threat as this virus has also been found to have some locking capability as well.

It spreads presenting itself as a legitimate app, such as WhatsApp and Pokemon Go. Once inside the system, GhostCtrl malware drops a malicious Android application package (APK) and opens the backdoor of the system to provide full access to the victim's personal information, videos and audios. It can also reset passwords and call or send texts to the victim's contacts.

Invisible Man. In July 2017, security experts discovered an updated and improved variant of Svpeng attacking banking app users in 23 countries. The virus spreads as a fake Flash Player app in the suspicious and insecure download websites. Fortunately, malware hasn't made it to the Google Play Store.

However, when users install this malicious app, they give administrator rights to the device. As a result, cyber criminals can control it via the Command and Control server.

The malicious program works a key-logger and collects credentials when a user logs in to the bank via a mobile app. Besides, Invisible Man malware can send and read messages, make and listen to phone calls, open phishing URLs, and collect various information. It also prevents victims from removing its administrative rights, so it's removal becomes complicated.

In the middle of August 2017, malware researchers discovered LeakerLocker spreading via two apps available on the Google Play Store. The malicious application was hiding under Wallpapers Blur HD” and “Booster & Cleaner Pro” apps.

One user "s installed one of these programs, malware locks device" s screen with a threatening message. According to it, this version of Android malware gained access to the sensitive data. If the victim "s don" t pay the ransom within 72 hours, all the information will be leaked.

However, security experts doubt that malware can cause such damage and recommend eliminating LeakerLocker from the device with security software.

In September 2017, malware researchers spotted a new version of the mobile malware. It spreads as a fake Adobe Flash update. After the attack, it locks the device by replacing the PIN. Then it launches data encryption and demands to pay 0.0130 Bitcoins to unlock the device and recover files.

Additionally, malware might also steal money from PayPal and banking accounts. Therefore, removal of the virus should be performed by ASAP. However, non-routed device owners might need to factory-reset infected phones to unlock it. Routed device users can use the Android Debug Bridge (ADB) tool. Further, DoubleLocker removal has to be completed with security software.

Lokibot virus. Infostealer.Lokibot is a malicious application designed for Android smartphones. Once it gets on victim's device, it becomes capable of sending SMS messages and replying to them, use mobile browsers, address particular URLs and install the SOCKS5 proxy.

As a result, the victim's outgoing traffic can be redirected. The virus can also compose and display fake notifications for the user, prompting the victim to open a bank account. As soon as the victim does so, the virus loads a fake overlay of the login page and collects all login details that the victim enters into the provided fields.

The extent of this Trojan virus is growing rapidly, because it is being sold on dark web forums for approximately $2000, meaning that any wannabe-criminal can buy it and distribute it.

In October 2017, LokiBot malware became capable of becoming a ransomware virus. However, this feature becomes active only in case the victim detects Infostealer.LokiBot and attempts to delete it. The malicious app fails to apply encryption on victim"s files but displays a screen-locking message anyway. The “Go_Crypt” function doesn't encrypt data but renames them anyway.

The screen-locking message says “ Your phone is locked for viewing child p0rnography,” and demands a payment of $100 within 48 hours. Otherwise, according to the virus, the case “will be handed over to the police.”

Marcher Android Trojan. alternatively known as ExoBot, the virus is known since 2013. However, in November researchers reported on a massive campaign that started in January 2017. The virus aims at Bank Austria users and tricks them into installing fake “Bank Austria Security App.” The recent version of the Marcher virus uses clever social engineering techniques to steal sensitive users" information, including banking credentials, date of birth, name, and other personally identifiable information.

Marcher distribution campaign is complicated. It brings malware to the smartphone, tries phishing credentials and stealing banking information, and finally emptying the victim's bank account. The biggest trick is that attackers use original Bank Austria design and interface. Users are advised to stay away from suspicious emails or SMS messages from this bank and check necessary information directly from the bank's website without clicking provided links in the phishing email.

Google reported about Tizi malware in November 2017. The virus works as spyware and is designed to steal personal information from social media apps, including Facebook, LinkedIn, Skype, WhatsApp, etc. Malware might also record calls, access SMS, take pictures and complete many other tasks that put Android user's privacy at risk.

Tizi virus might also get root access by exploiting system vulnerabilities or tricking a user into giving such permission during the installation of a malicious app. Some of the infected apps were available on the Google Play Store in 2015. However, the majority of them are spreading via third-party apps. At the moment, Google reports that about 1,300 Android devices were infected with the spyware.

General Android virus removal guide

If your device is infected with Android virus, you can run into these problems:

• The loss of sensitive information. Malicious apps that are used to infect Android OS can collect different kinds of data. Such information includes contacts, logins, e-mail addresses and similar information that is important for attackers.
• money loss. The most Android viruses are capable of sending messages to premium-rate numbers or subscribing users to premium services. This can lead you to the money loss and similar issues.
• Infiltration of malware. The android virus can try to take over your device and infect it with other malware. It can also cause annoying ads, pop-up alerts, and fake warning messages.
• performance-related issues. When infected with such a threat, you may notice system instability problems, slow downs, and similar problems.

If you think that your device is infected, we highly recommend you to scan it with or some other reliable Android virus cleaner. It will help you detect malicious files and other fraudulent components on your device. Sometimes block security software in order to avoid their elimination. If that is the case, you should reboot your Android device into Safe Mode before launching your Android antivirus to disable third-party apps (and malware as well) from running:

1. Find the power button and press it for a couple of seconds until you see a menu. Tap the power off.
2. Once you see a dialog window that offers you to reboot your Android to safe mode, select this option and OK.

If this failed to work for you, just turn off your device and then turn it on. Once it becomes active, try pressing and holding Menu, volume down, volume up or Volume Down and Volume Up together to see safe mode. If that doesn't work, then search the phrase “How to put into Safe mode” and add your phone's model. Then follow the instructions.

You can also try to perform Android virus removal manually by uninstalling the malicious app yourself. However, you should be very careful when trying to do so because you may remove useful files and apps from your device. For manual Android virus removal, please follow these steps:

1. Reboot your device into Safe Mode with the help of the steps that are given above.
2. When in safe mode, go to Settings. Once there, click on Apps or application manager(this may differ depending on your device).
3. Here, look malicious app(s) and uninstall all of them.

We also recommend turning off the option that allows installing apps that belong to unknown sources. For that, go to Settings -> Security. Once there, turn off this option.

The factory reset might be needed to remove Android malware

If nothing helps you remove Android malware from your phone or tablet, you should reset it to its factory settings. For that, you need to perform these steps:

1. Click the Compatible with Microsoft Windows Supported versions Compatible with OS X Supported versions What to do if failed?
   If you failed to remove virus damage using Reimage, to our support team and provide as many details as possible.

   Reimage is recommended to remove virus damage. Free scanner allows you to check whether your PC is infected or not. If you need to remove malware, you have to purchase the licensed version of Reimage malware removal tool.

“Darling, you need to get checked out. I’m embarrassed to say, but I think I picked up a… advertising banner somewhere.”

Yes, this is how you honestly need to admit to your loved one that a virus has got into your smartphone or tablet. Collective infection occurs not only somewhere on the Internet, but right in your home network. In I have already talked about the experience of dealing with advertising viruses and banners, and today I will add signs of infection and another sad experience with a good ending. The most difficult option for removing banners and viruses - when a virus enters the system, I described in the third post -

Part three. Banner on Android. Signs of infection

Have you seen these banners? How do you know if something is wrong with your favorite smartphone or tablet? Here are some signs that will help you identify if your device is infected. There may be many more signs, but here are the most frequent ones for the present and those that I have met more than twice.

Part four. How do I block ads?

So, annoying ads appeared - banners, full-screen pop-ups, transitions to pages of paid subscriptions. Google began to swear at the traffic coming from my network. What I've done? This experience is only mine and is not an instruction for use.

Note. As a source of infection or as a leaky application, there were also such: Caivs, slowly, Font manager, patriotic, etc.

This treatment worked on 3 devices. It is noteworthy that Asus and Samsung devices were not affected by me. Surprisingly, even the creepy Fly didn't get sick, but he was already disabled right on the assembly line. It is possible that this problem relates to Chinese devices with Android 4.4 kitkat.

In the following posts I will continue to tell the story of the fight against intrusive advertising. Stay tuned, ask, comment, share opinions. Good luck!

Why did your mobile phone suddenly start behaving differently than usual, or even “healed” with its “life”? Perhaps because she settled in it malware. Today, the number of viruses and trojans for Android is growing exponentially. Why? Yes, because the cunning guys-virus writers know that smartphones and tablets are increasingly used by our fellow citizens as electronic wallets, and do everything to move funds from the owners' accounts into their own pocket. Let's talk about how to understand that a mobile device has picked up an infection, how to remove a virus from Android and protect yourself from re-infection.

Symptoms of a virus infection on an Android device

• The gadget turns on longer than usual, slows down or suddenly reboots.
• In the history of SMS and phone calls, there are outgoing messages and calls that you did not make.
• Money is debited from your phone account by itself.
• Ads appear on the desktop or in the browser that are not associated with any application or site.
• Programs are installed by themselves, Wi-Fi, Bluetooth or a camera are turned on.
• Lost access to electronic wallets, mobile banking, or for unknown reasons, the amount in the accounts has decreased.
• Someone took over your account in social networks or instant messengers (if used on a mobile device).
• The gadget is blocked, and a message is displayed on the screen that you have violated something and must pay a fine or simply transfer money to someone for unlocking it.
• Applications suddenly stopped running, access to folders and files was lost, any device functions were blocked (for example, buttons are not pressed).
• When you start programs, messages pop up, like "an error occurred in the com.android.systemUI application."
• Unknown icons appeared in the application list, and unknown processes appeared in the task manager.
• The anti-virus program informs you about the detection of malicious objects.
• The anti-virus program was accidentally deleted from the device or does not start.
• Your phone or tablet battery is draining faster than usual.

Not all of these symptoms are 100% indicative of a virus, but each is a reason to immediately scan your device for infection.

The easiest way to remove a mobile virus

If the gadget has kept working, the easiest way to remove the virus is with the antivirus installed on Android. Run a full scan of the phone's flash memory, if a malicious object is detected, select the "Delete" option, saving the neutralized copy in quarantine (in case the antivirus mistook something safe for a virus).

Unfortunately, this method helps in about 30-40% of cases, since most malicious objects actively resist their removal. But there is control over them too. Next, we will look at options for when:

• the antivirus does not start, does not detect or remove the source of the problem;
• the malicious program is restored after removal;
• the device (or its individual functions) is blocked.

Removing malware in safe mode

If you can't clean your phone or tablet normally, try using the safe mode. The bulk of malicious programs (not only mobile ones) do not show any activity in safe mode and do not prevent destruction.

To boot the device into safe mode, press the on/off button, put your finger on "Power off" and hold it until the message "Entering safe mode" appears. After that click OK.

If you have old version Android - 4.0 and below, turn off the gadget in the usual way and turn it on again. When the Android logo appears on the screen, press the Volume Up and Volume Down keys at the same time. Hold them until the machine boots up completely.

While in safe mode, scan your device with an antivirus. If there is no antivirus or it does not start for some reason, install (or reinstall) it from Google Play.

In this way, advertising viruses such as Android.Gmobi 1 and Android.Gmobi.3 (according to Dr. Web classification) are successfully removed, which download various programs to the phone (in order to increase the rating), and also display banners and ads on the desktop.

If you have superuser (root) rights and you know exactly what caused the problem, launch a file manager (for example, Root explorer), follow the path where this file is located and delete it. Most often, mobile viruses and trojans place their bodies (executable files with the .apk extension) in the system/app directory.

To switch to normal mode, simply reboot the device.

Removing mobile viruses through a computer

Removing viruses on the phone through a computer helps out when the mobile antivirus does not cope with its task even in safe mode or the device functions are partially blocked.

It is also possible to remove a virus from a tablet and phone using a computer in two ways:

• using an antivirus installed on a PC;
• manually through a file manager for Android gadgets, for example, Android Commander.

Using an antivirus on a computer

To check files mobile device antivirus installed on your computer, connect your phone or tablet to the PC with a USB cable, choosing the "As a USB drive" method.

Then turn on USB.

After that, 2 additional “disks” will appear in the “Computer” folder on the PC - the internal memory of the phone and the SD card. To start scanning, open context menu each disk and click "Check for viruses".

Removing malware using Android Commander

Android Commander is a program for exchanging files between a mobile android gadget and a PC. Running on a computer, it provides the owner with access to the memory of a tablet or phone, allows you to copy, move and delete any data.

For full access to all the contents of the android gadget, you must first obtain root rights and enable USB debugging. The latter is activated through the service application "Settings" - "System" - "Developer Options".

Next, connect the gadget to the PC as a USB drive and run Android Commander with administrator rights. It, unlike Windows Explorer, displays protected system files and Android OS directories - just like, for example, in Root Explorer - a file manager for root users.

The right half of the Android Commander window shows the directories of the mobile device. Find the executable file of the application (with the .apk extension) that is causing the problem in them and delete it. Alternatively, copy suspicious folders from your phone to your computer and scan each of them with an antivirus.

What to do if the virus is not removed

If the above operations did not lead to anything, the malware still makes itself felt, and also if the operating system has ceased to function normally after cleaning, you will have to resort to one of the radical measures:

• reset with restoration of factory settings through the system menu;
• hard reset through the Recovery menu;
• flashing the device.

Any of these methods will bring the device to the state as after purchase - it will not have any user programs, personal settings, files and other information (data about SMS, calls, etc.). Your Google account will also be deleted. Therefore, if possible, transfer the phone book to the SIM card and copy paid applications and other valuable items to external media. It is advisable to do this manually - without using special programs, so as not to accidentally copy the virus. After that, proceed to the "treatment".

Restoring factory settings through the system menu

This option is the easiest. It can be used when the functions of the operating system and the device itself are not blocked.

Go to the Settings app, open the Personal - Backup section and select Factory Reset.

Hard reset via Recovery menu

A “hard” reset will help deal with malware if it is not removed by any of the above methods or has blocked the login. To our delight, access to the Recovery menu (system restore) is preserved.

Login to Recovery on different phones and tablets are carried out in their own way. On some, you need to hold down the “Volume +” key when turning it on, on others - “Volume -”, on the third - press a special recessed button, etc. The exact information is contained in the instructions for the device.

In the Recovery menu, select the option "wipe data / factory reset" or simply "factory reset".

flashing

Flashing is essentially a reinstallation of the Android OS, the same extreme measure as reinstalling Windows on the computer. It is resorted to in exceptional cases, for example, when a certain Chinese virus embedded directly into the firmware and lives on the device from the moment of its "birth". One such malware is the android spy 128 origin spyware.

To flash a phone or tablet, you will need root rights, a distribution kit (the firmware itself), an installation program, a computer with a USB cable, or an SD card. Remember that each gadget model has its own, individual firmware versions. They usually come with installation instructions.

How to Avoid Virus Infection of Android Devices

• Install mobile applications only from trusted sources, refuse hacked programs.
• Update your device as system updates are released - in them, developers close vulnerabilities that are used by viruses and trojans.
• Install a mobile antivirus and keep it always on.
• If the gadget serves as your wallet, do not let other people access the Internet from it or open unverified files on it.
