How to Remove Virus From Android
Remove Virus From Android. If you have problems with viruses on Android, the worry is fast – but you can get rid of a plague again. In the following we explain to you which measures you should absolutely take in an emergency. The smartphone behaves weird? Maybe you have a virus! And so you get rid of him again.
How to Remove Virus From Android
Android viruses are rare, but they exist. We’ll tell you how to remove a virus from Android and how to avoid Android malware in the first place.
The greatest chance of getting a virus on your Android smartphone is through the installation of dodgy apps. But even if you only get apps from the Google Play Store, you’re not completely on the safe side.
Remove Android Virus: How to succeed
You are not immune to malware on your Android either: In 2016, around 74% of all Android devices were malicious software. These can be annoying but harmless advertising popups as well as malware that reads personal data and passwords. With good antivirus protection, you will prevent your device from getting infected by malware in the future, as well as removing viruses that have already crept into your system.
If you decide to buy a very new app in the Google Play Store or install an APK , you theoretically run the risk of installing malware. Therefore, only use apps from trustworthy manufacturers. It’s a good indication if an app in the store already has a lot of user reviews. For new or barely used apps, Google might not have noticed any viruses and therefore could not ban the app from the store yet.
Also internet downloads and mails can contain viruses. If you suddenly have advertising on your mobile phone or something suspicious, you should install and run a virus scanner.
Reliable scanner for your Android
- Avira Antivirus Security
- Bitdefender Antivirus Free
- Kaspersky Internet Security
The scanners and firewalls are easy to download from the Google Play Store and can be used for free. Regular scans improve your safety. If your virus can not be removed, you will most likely need to reset your Android to factory settings or have it repaired.
Malware on Android
If you take it exactly, viruses under Android are actually not a problem, because strictly speaking (almost) they do not exist. These self-reproducing dark ones are no longer the big issue even on Windows today, but the name is left over: you can confidently consider virus as a synonym for malware, that is, any kind of unwanted, malicious software. And under Android this is usually very simple: Apps.
The classic virus was able to spread itself and cause damage everywhere, often optimizing itself independently. But today, hardly anyone is interested in destroying your device. Your data and possibly your computing power are very exciting for attackers. And blackmail with the encryption of your data sounds lucrative.
But Android is much more secure than Windows. Programs can not simply download other programs and even clicking on a wrong link usually brings no app on the device. Rights must be granted explicitly under Android and by default can be installed anyway only from Google Play and possibly the Appstores of the manufacturer.
However, there were cases in which apps have actually sneaked over some detours on smartphones, but more normal, the gateway is easy to locate: It sits in front of the smartphone … Even the big hacker attacks on companies and authorities are mostly under gracious With the help of staff – the famous email attachment is still one of the biggest problems.
If an attacker manages to place a malicious app on Google Play or manipulate an app in another reputable store, all he has to do is wait for someone to install it. Before you can remove it, there are two prevention tips: Do not blindly go on “Next”, look carefully at what you are installing ( keyword fake apps ) and grant only the rights an app really needs. And maybe you’ll go for an anti-virus program . Opinions vary, but basically an anti-malware program is a good idea.
Unfortunately Android does not announce itself: “Here is a virus”. Anti-malware apps do that, of course, but only as far as that is possible. If the typical virus has actually been installed and authorized by you, for example, as a game, anti-malware will not necessarily help. But there are symptoms, of course.
A malware, for example, could tap into the computing power of the smartphone to generate cryptocurrencies – then you’ll notice that on a slow, possibly even jerky system . Even if there are suddenly constantly unwanted notifications and noticeably much advertisingThis could be a cause for concern.
For analysis, you can use any of the apps to monitor processes and network connections, such as Simple System Monitor , where you can quickly and easily find out which app consumes extra bandwidth or processing power. But the best truffle pig is yourself: just look through the list of apps – most malware, as I said, is nothing more than an app. And what you did not install and was not preinstalled by the manufacturer may tend to go away.
By the way: A kind of virus reports then very rabid – the ransomware. If you suddenly see only a warning message on the whole screen that can not be removed, you may be affected. Or it is really just a picture, so a fake blackmail. Even in such cases you can bring about the safe mode the solution.
Getting rid of it is not that complicated: launch Android in safe mode and uninstall the malware app. The safe mode you may know from Windows, here it is quite similar: Android starts almost in the nude version, only with the original apps and settings. And in this mode, malware can be easily uninstalled.
Unfortunately, they do not always come in the same way in this mode, which varies from manufacturer to manufacturer – and sometimes solutions are also changed by updates. Therefore, the following instructions are always to be seen with a little skepticism. If something does not work, just try the other variant.
- Standard solution for many devices with only moderately modified Android systems, such as Huawai, Google, Motorola :
- Hold down the power button until the menu appears.
- Press and hold down the Power Off button (if applicable, Restart ) until the option ” Run in Safe Mode ” appears and select it.
Some systems provide extra startup options with a long press, here a Nexus 5 with Lineage OS.
- Alternative solution that works here for example on the Honor 6X and also on Samsung devices:
- Turn off the smartphone completely .
- Start as usual.
- Press and hold down the Volume Down key as soon as the (first) manufacturer logo has disappeared. If that does not work:
- Press and hold down the volume down button (on Samsung also menu button), as soon as the manufacturer logo appears.
In both cases, the message ” Safe Mode ” appears at the bottom left and Android starts up accordingly.
n safe mode you will always see the corresponding hint in the lower left corner.
After the start, you can then uninstall the apps . You will no longer find them on your screens, but only via ” Settings / Apps “. To exit the safe mode you just have to restart.
Uninstalling is only possible via ” Settings / Apps “.
Of course there is also the radical solution: Reset the device completely to factory settings . You will find this option under ” Settings / Advanced Settings / Backup and Reset “. You can exclude your actual files and app settings can be restored later using the ” Automatic Restore ” option . Both of these save a lot of time, but you must remember that you ‘ll need to reinstall all the apps , which can be time consuming. Make sure that the device is then again guaranteed malware-free.
Now your smartphone is free of viruses and everything is running – but you are not done yet! You should urgently change your passwords, if possible from all accounts and services running on the device. And best of all, do that between resetting and restoring the system.
Of course, apps are not so easy on passwords, but there are always opportunities and gaps. For example, reading passwords from the clipboard might be an option. Or also insecure password manager.
After a reset, you are well-positioned with Android’s default settings. But if you just uninstalled individual apps, you should also check if any settings are not safe. First and foremost, allowing installations away from Google Play and possibly a manufacturer-owned store should prevent you – maybe you have used it at some point and then not disabled again.
Also the account settings are worth checking: Are only the desired accounts connected? Or has something crept in or been forgotten?
And ultimately, even over-privileged apps could have been the gateway for the malware. So also here: Check.
One last tip: Usually, malware wants to connect to the Internet. And you can control that on Android as well as on Windows, with a firewall . It will help you even more with the analysis.
Where do Android viruses come from?
You notice a very sluggish behavior of your device. It could be a virus, but it does not have to. Or you may receive a notice that your device is infected and that you need to download an app – but then be careful!
First and foremost, Android viruses come in the background of a normal app on your smartphone or tablet. That’s true of all the big Android viruses that made headlines in recent years: Gunpoder, Ghost Trojan, Googlian and Godless all installed in this way. Mazar, on the other hand, sneaks in on a text message requesting that the Tor Browser be downloaded. What you should not do, of course, because of such a message!
Also Loapi comes from outside the Google Play Store. This Trojan is a nasty threat. It comes with antivirus programs that users install in the belief that they are protected. Loapi can put so much strain on your device that it overheats and destroys the battery. The Trojan can send text messages on your behalf, it can subscribe to paid services without your knowledge, allow attackers to execute HTTP requests for DDoS attacks, and generate the crypto currency Monero.
Skygofree is another malware. It will be installed on your device via download links on fake websites that are the official sites of well-known brands, such as mobile operators.
The goals of the Android viruses are different. Some let malicious processes run on your device, others steal your personal information, and others download additional software that is not always malicious. However, you simply do not want to have these pests on your own devices.
How to avoid Android viruses and malware
Do not install applications outside of Google Play. To prevent this from happening, this feature should be disabled by default. Check this: Open the settings menu on your smartphone or tablet, go to “Security” – the “Unknown sources” option must be disabled.
If you install an application that is not on the Google Play Store, you should be absolutely sure that you are installing it from a legitimate source, not a fake website that claims to be the official source.
Avoid cloned applications: 99% download apps safely from Google Play, but it’s still found malicious code in applications. Do not download seemingly cloned applications from unknown developers.
Check the permissions of the app: Regardless of where you install an application, verify the permissions you need before you click Install. Never assign admin rights to an app that would prevent it from being deleted. And does a video player really need to see your contacts?
Keep Android Up to Date: The latest version of the Android operating system may not be available on your phone or tablet, but you should make sure your device is as up-to-date as possible.
remove virus from Android
Bring your phone or tablet into safe mode. This prevents third-party applications, including malware, from running.
On many devices, you can press the power button to access the power off options. Then press and hold the power button to invoke an option to reboot in safe mode.
If that does not work for your device, search Google ‘ How to put [your model name] into safe mode ‘ and follow the instructions.
Open your settings menu and select “Apps”, then make sure you see the “Downloaded” tab (this depends on the version of Android you are running).
You may have a good chance of knowing when your device started to stop working normally, and maybe you can associate that with downloading a particular app.
If you do not know the name of the application that you believe has infected your smartphone or tablet, go through the list of applications and look for something that looks doubtful or that you do not know is installed should or should not run on your device.
Tap the malicious application to open the app info page, and then click Uninstall.
In most cases, this is all you need to do to remove the virus, but occasionally the Uninstall button is greyed out.
This is because the virus has given itself the status of a device administrator.
Exit the Apps menu and tap “Settings, Security, Device Administrators.” Here is a list of all apps on your phone or tablet with admin status. Uncheck the box for the application you want to remove and tap Disable on the next screen.
You should now be able to return to the app menu and remove this app.
Because the virus no longer exists on your Android phone or tablet, you only need to restart the device to remove it from Safe Mode.
