How to Remove Viruses from Your Phone

Co-authored by Mobile Kangaroo and Travis Boylls

Last Updated: May 11, 2023

This wikiHow teaches you how to clear viruses from your phone using an antivirus app, booting your phone into safe mode to uninstall problem apps, and restoring your phone from a backup. Viruses on a mobile phone usually come from apps that are downloaded outside of the Google Play Store on Android devices. Viruses on iPhones are rare because Apple has much more stringent controls on the apps they allow on iOS devices.

Method 1

Method 1 of 3:

Using Antivirus Apps on Android

1
Install Avast Antivirus. Avast Antivirus is a free antivirus app that can be downloaded from the Google Play Store:
- Open the Google Play Store .
- Type avast in the search bar.
- Tap the Avast Antivirus app.
- Tap Install .
You can open it by tapping the app icon on your home screen or tap Open in the Play Store once it's finished installing.

4
Tap Scan . It's the large orange button at the top of the screen.
- Tap Allow to grant the app permissions to scan your phone.
If there are no threats detected, the app will say "You are protected." ^{[1]

- On Pixel , Nexus , and other Stock Android devices:
  - Press and hold the power button on the right side of your phone.
  - Tap and hold Power Off .
  - Tap Ok when you see " Reboot to safe mode ".
- On Samsung Galaxy devices.
  - Press and hold the power button on the right side of your phone.
  - Tap Power Off .

  - Release the power button when you see the Samsung animated logo.
  - Press and hold the volume down button until your phone boots up in safe mode.
The Settings app has an icon that resembles a gear and is typically found in your phone's app drawer.
It's next to the icon that has four circles. This will display a list of all the apps installed. Tap the Downloaded tab, if it is available on your device.
Apps are listed in alphabetical order. If you don't know the name of the app that is causing problems, look for apps you didn't install yourself, or apps you installed around the time your phone started having problems.
5
Tap Uninstall . This will uninstall the app. In some cases, the "Uninstall" button may be grayed out, making the "Uninstall" option unavailable. This happens when the app grants itself administrative privileges. If this is the case, use the following steps to remove administrative privileges from the app.
- Tap the Back arrow to exit the apps list.
- Tap the Security tab in "Settings"
- Tap Device Administrators . You may have to tap "Other security settings", depending on your device.
- Tap any app you don't want to have administrative privileges.
- Tap Deactivate . This will remove the apps administrative privileges. You can now uninstall the app. ^{[3]

Method 3

Method 3 of 3:

Troubleshooting on iPhone

Viruses on iPhone are so rare that it's unlikely you have a virus on your iPhone. Occasionally, however, apps can be compromised without the developers even being aware. If you are experiencing problems while one app is open, open the App Store, tap the "Updates" tab and see if there is an update for that app. If an update is available, tap "Update" to install the latest updates. If an update is not available, see if you can contact the app developers and report the problems.
If no update is available for the problem app, simply tap and hold the icon on the home screen until all the apps start twitching. Tap the "x" button in the upper-left corner of the app icon to remove the app.
3
Restore your iPhone. If you have removed problem apps from your iPhone and you are still having problems, you may need to restore your iPhone. If you have a previous backup of your phone, you can restore your phone from a backup. The way you restore your phone from a backup depends on the method you used to back up your iPhone. If you do not have a backup of your iPhone, you may need to reset your iPhone to its factory settings. ^{[4]

Question

My phone is having difficulty operating. When I try to swipe down to see my notifications, it is very difficult to do. Before this happened, I received a text message from an unknown sender. Is it a virus?

Community Answer

If the message you received contained a link in it, do not click on it. It almost always has a virus connected to the page it sends you to. The same goes for emails. Do not investigate suspicious links.

Question

My percentage doesn’t last long is it a virus?

Community Answer

It depends. You may have a lot of open windows. Try to close them when you don't need them. If you use any type of live wallpaper, it will decrease your battery percentage in no time. You may also have a cryprominer. When you download files and games from unknown sources they may contain cryprominer. A cryprominer mines 24/7 bitcoin from your phone and the profit is being sent to the attacker. When a phone is infected with these types of malware, their battery percentage decreases a lot faster than usual.

Question

I had Minecraft on my phone, then one day it randomly uninstalled. I swear I didn't do anything. Is this a virus?

Community Answer

It depends. If you downloaded from an unofficial source (for example happymod or other pirating websites) then yes it may contains viruses, trojans or other malicious files. If you bought it from a trusted source (Play store or app store) then you must check suspicious files or apps on your phone and if you still think you have a virus, the best solution is to go to an expert.

Only download apps from official sources. To avoid viruses, make sure you only install apps from the Google Play Store or App Store. Avoid installing APK files on Android, and don't use jailbroken iPhone devices.
