How to scan your Android phone for viruses right now

The fastest way to check your Android phone for viruses is to use Google Play Protect, which is built into every Android device and runs scans automatically. Open the Google Play Store app, tap your profile icon in the top right, select "Manage apps and device," then tap the "Manage" tab. If you see a green checkmark and "All apps scanned," your phone passed the most recent scan. If it shows a warning, tap "Scan" to run a new check immediately.

Google Play Protect scans apps you download from the official Google Play Store before and after installation. It also monitors apps already on your phone for suspicious behavior. This catches most common threats because Google reviews millions of apps daily. However, if you downloaded apps from outside the Play Store or sideloaded files, you may need a second opinion from a dedicated antivirus app.

If Google Play Protect finds something, it will show you the app name and what it detected. You can then uninstall the app directly from that warning screen. The scan takes a few minutes and runs in the background, so you can use your phone while it works.

Key Takeaways

  • Google Play Protect is built into Android and scans your phone automatically, so you do not need to download anything to run a basic virus check.
  • If you downloaded apps from sources other than the Google Play Store, consider running a scan with a dedicated antivirus app like Malwarebytes or Avast to catch threats Google Play Protect might miss.
  • A virus scan takes a few minutes and runs in the background without interrupting normal phone use.
  • If a scan finds malware, uninstall the suspicious app immediately and change passwords for sensitive accounts like email and banking.
  • Viruses on Android are rare compared to other threats, but malicious apps that steal data or display unwanted ads are common and preventable by downloading only from the Play Store.

Understanding what Google Play Protect actually checks

Google Play Protect does not catch every threat, and understanding its limits helps you know when to use other tools. It scans apps for known malware signatures — patterns that match viruses and malicious software Google has already seen. It also watches for suspicious behavior, like an app trying to access your contacts without permission or sending data to unknown servers.

The system works well for apps in the Google Play Store because Google reviews them before they go live. However, if you sideload an app — download it from a website or email instead of the Play Store — Google Play Protect may not scan it until after you install it. Sideloaded apps are where most Android malware lives, because they bypass Google's initial review.

Google Play Protect also cannot detect every new threat. Malware developers create new variants constantly, and a brand-new malicious app might not match any known signature yet. This is why security experts recommend a layered approach: use Google Play Protect as your first line of defense, but add a second scan if you have downloaded apps from outside the Play Store or if you notice unusual phone behavior.

When to use a dedicated antivirus app

A dedicated antivirus app like Malwarebytes, Avast, or Norton is worth running if you have sideloaded apps, visited risky websites, or notice your phone acting strangely. These apps use different detection methods than Google Play Protect — they may catch threats that Google's system misses, especially older malware or regional variants. Download one of these from the Google Play Store, install it, and run a full scan. The process is similar to Google Play Protect: open the app, tap "Scan," and wait for results.

Dedicated antivirus apps do slow down your phone slightly because they run background monitoring in addition to scans. If you use one, you do not need to run it constantly — a weekly scan is enough for most people. Some antivirus apps also offer real-time protection, which watches for threats as you use your phone, but this drains battery faster.

Free versions of these apps scan for viruses but may show ads or limit features. Paid versions remove ads and add features like real-time protection or VPN service. For most users, the free version is sufficient for occasional scans.

Signs your Android phone might have malware

Certain behaviors suggest your phone has picked up malware, even if a scan has not found anything yet. If your phone is unusually slow, drains battery much faster than normal, or gets hot during light use, malware running in the background could be the cause. If you see pop-up ads appearing outside of apps, or if apps crash frequently, those are also common signs.

Watch for unexpected data usage. Open Settings, go to "Network and internet" or "Connections," then tap "Data usage" or "Mobile data." If the total is much higher than usual, a malicious app may be uploading data without your knowledge. Similarly, if you notice charges on your phone bill for services you did not sign up for, malware may be subscribing to premium content.

If you notice any of these signs, run a scan with Google Play Protect first, then follow up with a dedicated antivirus app. After the scan, restart your phone in Safe Mode to see if the problem persists. Safe Mode disables all third-party apps, so if the phone runs normally in Safe Mode, a recently installed app is likely the culprit. To enter Safe Mode, press and hold the power button, then press and hold "Power off" until a "Safe Mode" option appears.

How to remove malware after a scan finds it

When a scan detects malware, the antivirus app will show you the app name and offer to remove it. Tap the removal option — usually labeled "Remove," "Uninstall," or "Quarantine." The app will then delete the malicious software from your phone. After removal, restart your phone to clear any remaining traces from memory.

After removing malware, change your passwords for sensitive accounts, especially email, banking, and social media. Malware often steals login credentials, so changing passwords prevents the attacker from accessing your accounts even if they captured your old password. Use a strong password: at least 12 characters mixing uppercase, lowercase, numbers, and symbols.

If the malware was a banking or payment app, contact your bank or payment service to report the incident. They can monitor your account for fraudulent charges and may cancel your card as a precaution. If the malware was a messaging or social media app, let your contacts know your account may have been compromised, so they do not click links sent from your account.

Preventing malware on Android going forward

The simplest way to avoid malware is to download apps only from the Google Play Store. Google reviews every app before it goes live and removes malicious ones quickly when they are discovered. Third-party app stores and direct downloads from websites have much less oversight, which is why they harbor most Android malware.

Before installing any app, check the reviews and permissions it requests. If a flashlight app asks for access to your contacts or location, that is a red flag — it does not need those permissions to work. Tap "Permissions" in the app's Play Store listing to see what it wants access to. Legitimate apps request only the permissions they actually need.

Keep your Android operating system updated. Google releases security patches regularly, and updating closes vulnerabilities that malware exploits. Go to Settings, tap "About phone," then look for "System update" or "Software update." If an update is available, install it as soon as possible. Also update your apps regularly — malicious developers sometimes push malware through app updates, but Google catches and removes these quickly.

Frequently Asked Questions

Can Android phones get viruses like computers do?

Android phones can get malware, but true viruses that replicate themselves are extremely rare. Most Android threats are malicious apps that steal data, display ads, or subscribe you to paid services. These behave differently from computer viruses but cause similar problems. Google Play Protect and antivirus apps catch both types.

Does running a virus scan slow down my phone?

A scan may use extra battery and processing power while it runs, but it does not permanently slow your phone. Once the scan finishes, performance returns to normal. Running a scan once a week or once a month has no lasting impact on speed.

What if Google Play Protect says my phone is infected but I cannot find the app?

Sometimes malware hides its icon so you cannot see it in your app list. If Google Play Protect identifies an infected app but you cannot find it to uninstall, tap the warning in Play Protect and select the removal option. Google Play Protect can uninstall apps even if they are hidden. If the warning persists after removal, restart your phone and run the scan again.

Is it safe to use free antivirus apps?

Free antivirus apps from established companies like Malwarebytes, Avast, and Norton are safe to use. They are legitimate tools that scan for malware. However, some unknown or heavily discounted antivirus apps may themselves be malicious. Stick to well-known names available in the Google Play Store with thousands of reviews.

Will a virus scan find spyware or stalkerware?

Standard antivirus scans catch some spyware, but not all. Stalkerware designed to track someone's location or messages may evade detection because it mimics legitimate monitoring apps. If you suspect someone is tracking your phone, consider a factory reset as a last resort, which erases everything and removes hidden software. Back up your important data first.
