Antivirus AI by Protectstar is an AI-powered antivirus and virus scanner for Android. Scan apps, files and downloaded APKs for viruses, malware and spyware. Review what is detected and decide what to remove, with no ads interrupting your scan.
Start with FREE manual scans without a subscription. For protection between checks, PRO adds real-time malware protection in the background and scheduled scans.
Check what you install and download
Your phone holds the messages, photos and information you use every day. Use an antivirus scan to check unfamiliar software and downloaded files before you use them.
• Scan installed apps and saved files for malware.
• Check a downloaded APK before installing it.
• Scan an unfamiliar saved attachment before opening it.
• Look for spyware, ransomware and banking trojans.
• Detect harmful adware and potentially unwanted apps.
A download from a new source or an app you do not recognise is a reason to check. Unexpected pop-ups may also prompt a scan. An app's name or icon alone cannot tell you whether it is safe. Review the findings alongside the source of the download when deciding what to install.
Two engines, complementary analysis
Dual Engine combines known malware signatures with AI pattern analysis. Signatures help identify familiar threats. AI examines suspicious patterns that may indicate new or disguised malware. The approaches complement each other when assessing software on your phone.
Deep Detective adds heuristic checks for suspicious characteristics. Protectstar AI CLOUD supports threat checks and the distribution of updated protection rules. Together, these technologies help turn a scan into findings you can review and act on.
From a finding to a clear next step
Open a result to see which app or file is affected. Read the information before taking action. Delete a harmful file or follow Android's steps to uninstall a malicious app. You choose what to remove from your device.
After taking action, run another scan to look for remaining detectable threats. A scan cannot guarantee that every threat will be found. Keep Android and your apps updated as part of your security routine.
Choose protection for everyday use
• FREE: manual antivirus scans without a subscription.
• PRO: real-time background protection and scheduled scans.
• GOV: all PRO features, experimental protection rules (beta) and priority support.
Use FREE for checks you start yourself. Choose PRO to schedule scans and add protection while you use other apps. Compare the features in the app to select the edition that fits your routine. You can still run a manual scan whenever you need one.
