What is Android malware?

Signs your Android might have malware

Malware may leave some telltale signs on your device. Be on the lookout for these issues.

4. An unexpected app appears

If any of these previous symptoms make you suspicious, then you’ll want to take a look at what apps are installed on your phone. Head into Settings, tap on Apps and expand the list to see what’s there. Look for any apps you don’t recognize or don’t remember installing.

One tactic is for malware apps to install themselves then disappear. Those leave a telltale blank spot in your app drawer.

How to remove a malware app on Android

If you think you’ve got a malicious app hanging out on your Android device, then it’s time to make it disappear. First, put your phone into Safe Mode, which disables third-party apps.

The method for doing this may vary with your phone, but for most, it involves holding down the power key then tapping and holding Power off. Tap OK when prompted to reboot into Safe Mode.

Now let’s remove the offending app. Open Settings and tap on Apps & notifications. You may need to tap on the see all option for the complete app list. Locate the problem program and click Uninstall. Restart your phone or tablet like normal to return to the regular operating mode.

Protect your Android device from malware

Once you’ve removed an offending malware program, you’ll want to make sure your device stays safe and secure. Follow these steps to help keep your Android gadget malware-free:

Be wary of all app downloads — even from the Google Play store

There are so many issues with Google Play that the company can’t even keep up. Infected apps and outright malicious apps are downloaded by unsuspecting victims daily, so a good rule of thumb is to never download an app unless you know it’s safe. Tap or click here to learn how to tell if a Google Play app is safe.

Install the latest updates

Keep both your Android system and your apps updated in order to take advantage of the latest security improvements. Better yet, set up automatic updates for your apps by opening the Google Play app, tapping Menu then Settings, go to Auto-update apps and select how you want them to update.

Consider anti-malware software

There are plenty of options for Android antivirus apps. At their best, these apps can prevent malware attacks and also scan your phone or tablet to locate existing malicious software.

Research shows many antivirus options are ineffective, so be sure to go with a known security provider with a good track record. Tap or click to see why free antivirus software isn’t enough.

Be vigilant
