Google’s ecosystem may be increasingly safe thanks to constant improvements to Play Protect, but that doesn’t mean the chances of downloading an infected app are completely zero. Security and antivirus apps are great, too, but what if your device is already infected? If your Android device is suddenly slow, using too much data, or showing corrupted data, then you could have downloaded an app infected with malware — or the much more obvious ransomware. Suspect apps — often promising free work software, cheat codes, new games, porn, or money — are an increasingly common method of getting viruses onto your mobile devices, where they wreak havoc and steal data.
If you can still access your Android device, your first step should be to get rid of the infected app, before it tries to infect other devices or does more damage. Here’s how to locate and remove Android malware, along with a few options for security downloads to help protect you in the future.
Shut down until you find out the specifics
Once you’re sure your phone is under attack by malware, hold the power button down and turn the phone fully off. It may not stop the malware from causing damage, but it can stop the problem from getting worse, and may halt ongoing malware attempts to access nearby networks.
Shutting down also gives you time to think and research. Do you know the specific infected app that brought malware onto your device? Do you know what other types of software it may have downloaded without your consent? If not, then move to another computer and look up your symptoms (as well as any new apps you tried out) to narrow down the issue. If you can’t find the app at the root of the problem, you can’t remove it.
If your research turns up nothing, you may want to turn your phone back on and skip down briefly down to step five. Anti-malware apps can help identify what is causing your problems and may even be able to remove the infected software for you. However, this will also require giving your phone access to the internet again, which involves some risk.
Switch to safe/emergency mode while you work
When you turn your device back on and plunge back in to isolate the problematic app, switch over to safe mode first. This will help limit the damage the infected app can do.
For most Android devices, you can switch to safe mode by holding down the power button for a couple seconds when your device is on, then tapping and holding on the Power off option. This should bring up a few power options, including the option to Reboot to safe mode. Choose this mode and wait for your phone to reboot before you continue. If you can’t find a safe mode, activate airplane mode instead, to cut your device off from any networks. You can usually find that option at the top of your notifications shade.
Note: If you can’t find out what’s causing your malware problem, even after downloading a security app, this is not the time to tinker. Ask a professional for help and if you should wipe your phone. This is a good strategy if increasingly common ransomware takes over your phone and blocks your actions.
Head to Settings and find the app
Visit Settings on your Android device. Settings typically has a gear-shaped icon, but that depends on your themes and arrangement: Search for it if you have trouble locating the right spot.
In Settings, scroll until you see the section called Apps, and enter. Look for a list of all your current apps — you may need to choose App Manager to locate the full list. Once there, scroll until you find the infected app at the center of your problems.
Select the app, and this should bring up options to Uninstall or Force close (often you cannot uninstall core apps, only disable them, but these apps are unlikely to be the problem).
Delete the infected app and anything else suspicious
Simply choose Uninstall, and your Android device should remove the app in question. It’s also a good idea to review your app list and uninstall other suspicious downloads — if you haven’t looked at this list before, you may be surprised at some of the odd things your device will automatically download.
Note: In some cases, you can’t uninstall the app, and the option itself won’t be there — you’ll see Disable in its place. Some of the most clever malware/ransomware will visit your administrator settings and give itself special protection to prevent this very thing. Fortunately, it’s often easy to fix. Go back to the original Settings menu and scroll down to Lock Screen and Security (or a similar corresponding section). In the Security menu, look for a section that says “Phone (Device) Administrators.” You may need to visit “Other security settings” first, depending on how your security menu is set up. In Phone Administrators, you should be able to enable the ability to remove Android malware.
Download some malware protection
A vulnerable Android device deserves protection. There are a number of security apps you can download to help protect your phone, scan for viruses, and get rid of junk files and any potentially infected software. When you are finished manually deleting the troublesome app, download a security program to help take care of any future issues. There are many choices in this field: Try software like 360 Security, Avast Security, or AVG Antivirus from the Google Play Store, or take a look at our other Android security recommendations here.
While it sounds obvious, it’s also a really good idea to keep your Android device constantly updated. Forgetting to update is one of the key factors that can leave Android phones open to attack.
