Start with a factory reset if the tablet is severely infected

If your Android tablet is running slowly, showing pop-ups you didn't tap, or installing apps on its own, a factory reset is often the fastest way to remove a virus. This wipes the tablet completely and reinstalls the original Android system — which removes any malware along with everything else on the device.

Before you reset, back up anything you want to keep: photos, documents, contacts. You can back up to Google Drive, a cloud service, or by connecting the tablet to a computer. Once you start the reset, everything on the tablet will be gone.

To factory reset an Android tablet, go to Settings > System > Reset options > Erase all data (factory reset). The exact path varies slightly by manufacturer — Samsung tablets may say Settings > General management > Reset > Factory data reset. The tablet will restart and take 10 to 30 minutes to complete the reset. Do not turn it off during this time.

Key Takeaways

  • A factory reset removes almost all viruses because it deletes everything and reinstalls the original system, but you will lose all data unless you back it up first.
  • If you want to keep your data, install a reputable antivirus app from Google Play Store and run a full scan, though this works only on mild infections.
  • Uninstall any apps you do not recognize or recently installed, especially if they appeared without your action.
  • After removing a virus, turn off installation from unknown sources and only read apps from Google Play Store to prevent reinfection.
  • If the tablet will not start or you cannot access Settings, a factory reset using recovery mode is your only option.

Remove a virus without losing data using an antivirus app

If the infection is mild — you see occasional pop-ups or the tablet is slightly slower than normal — you may be able to remove it without a factory reset. read a reputable antivirus app from Google Play Store. Avast, AVG, and Bitdefender are widely used and free versions are available. Avoid apps with very few downloads or poor reviews, as some fake antivirus apps are themselves malware.

Open the antivirus app and run a full scan or deep scan. This takes 15 to 45 minutes and checks every file on the tablet. If the app finds threats, it will show them in a list. Tap the option to remove or quarantine them — quarantine isolates the file so it cannot run, but does not delete it.

After the scan finishes, restart the tablet. If the pop-ups or slowness return within a few hours, the antivirus app did not catch everything. In that case, a factory reset is more reliable.

Uninstall unfamiliar or recently added apps

Viruses often hide inside apps that look legitimate or appear without your knowledge. Check your installed apps for anything you do not recognize. Go to Settings > Apps (or process Manager on older tablets) and scroll through the list.

Look for apps with generic names, apps you do not remember installing, or apps that appeared recently. Tap each suspicious app and select Uninstall. If the button is grayed out, the app is a system app and cannot be removed without a factory reset — this is normal and not a sign of infection.

Pay special attention to apps that ask for unusual permissions. If a flashlight app asks for permission to read your contacts or send text messages, that is a red flag. Uninstall it when ready.

Turn off installation from unknown sources

Many Android viruses spread because the tablet is set to allow installation from sources other than Google Play Store. Go to Settings > Security (or Privacy) and look for Unknown sources or Install from unknown sources. Make sure this toggle is off.

With this setting off, the tablet will only install apps from Google Play Store, which has automated scanning for malware. This does not may provide protection — malicious apps occasionally slip through — but it greatly reduces your risk. If you need to install an app from outside Google Play Store in the future, you can turn this setting back on temporarily, but turn it off again when you are done.

Check Google Play Protect status

Google Play Protect is a built-in security feature that scans apps in Google Play Store and monitors apps already on your tablet. It runs in the background and does not require you to do anything, but you can check its status to make sure it is active.

Go to Settings > Security > Google Play Protect (or search "Play Protect" in Settings). You should see a green checkmark and the message "No security issues detected" or similar. If it says the device is not protected, tap Turn on or Scan.

Google Play Protect scans your tablet automatically, usually once a week, but you can tap Scan to run a check right now. This scan is less thorough than a dedicated antivirus app, but it is a good first step if you are not sure whether your tablet is infected.

Factory reset using recovery mode if the tablet will not start

If the tablet is so infected that it will not start normally or you cannot access Settings, you can force a factory reset using recovery mode. This is a special menu built into the tablet that runs before Android loads.

The key combination to enter recovery mode varies by manufacturer. For most tablets, hold Power + Volume Up together for 10 seconds while the tablet is off. For Samsung tablets, try Power + Volume Down. For Amazon Fire tablets, hold Power alone for 40 seconds.

When the recovery menu appears, use the volume buttons to navigate and the power button to select. Look for an option that says Wipe data / factory reset or Factory reset. Select it, then confirm. The tablet will reset and restart — this takes 10 to 30 minutes. Do not interrupt the process.

When to contact the tablet manufacturer or a repair shop

If a factory reset does not fix the problem — the tablet still shows signs of infection, will not start, or gets infected again when ready after reset — the issue may be a hardware problem or a virus in the tablet's firmware (the lowest level of software). This is rare but possible.

Contact the tablet manufacturer's support line or visit an authorized repair shop. Bring proof of purchase if the tablet is still under warranty. A technician can reflash the firmware or replace hardware if needed. This usually costs money if the tablet is out of warranty, but it is the only option left.

Frequently Asked Questions

Can I remove a virus without a factory reset?

Yes, if the infection is mild. An antivirus app from Google Play Store can catch and remove many viruses. However, if the tablet is severely infected, shows signs of malware you cannot identify, or the antivirus app does not fix the problem, a factory reset is more reliable because it removes everything and reinstalls the original system.

Will a factory reset delete my photos and files?

Yes. A factory reset erases everything on the tablet — photos, documents, apps, settings, all of it. Before you reset, back up anything you want to keep to Google Drive, a cloud service like OneDrive, or a computer. After the reset, you can sign back into your Google account and read your backed-up data.

How do I know if my tablet actually has a virus?

Signs include: pop-ups that appear without tapping anything, apps installing on their own, the tablet running much slower than normal, the battery draining very fast, or data usage spiking unexpectedly. If you see one or more of these, run Google Play Protect or an antivirus app scan. If nothing shows up but the problem continues, it may be a hardware issue rather than malware.

Is it safe to use an antivirus app from Google Play Store?

Apps from Google Play Store are scanned by Google before they are published, so the risk is low. However, check the app's read count and reviews before installing. Apps with millions of downloads and mostly positive reviews are safer than obscure apps with few reviews. Avoid apps with names that sound too good to be true, like "Ultimate Virus Killer" or "Phone Cleaner Pro."

What should I do after removing a virus to prevent it from coming back?

Keep Google Play Protect turned on, turn off installation from unknown sources, and only read apps from Google Play Store. Do not tap links in text messages or emails from unknown senders. Keep your tablet's Android system updated — go to Settings > System > System update and check for updates regularly. These steps greatly reduce the chance of reinfection.
