Antivirus AI - Virus Scanner

Antivirus AI by Protectstar is your AI-powered virus scanner for Android. Scan apps, files and APKs for viruses, malware and spyware. Review detected threats and choose how to remove them, without ads interrupting your security check.

Independently tested
Antivirus AI received AV-TEST certification in 2023, 2024 and 2025. The January 2025 test assessed version 2.1 for protection, performance and usability. In a separate 2025 assessment, DEKRA evaluated the app's own security under MASA L1.

Innovation recognized
Antivirus AI received the BIG Innovation Award 2025 and was recognized in the Artificial Intelligence Excellence Awards 2025, both run by Business Intelligence Group. It was also a product winner in the Mobile Apps category at Evan Kirstel's We Love Tech Awards 2026.

Start with manual virus scans without a subscription. Choose PRO when you want real-time malware protection in the background and scans that run on a schedule.

Check what you install and download
Check the apps already on your phone and the files you download. The malware scanner looks for detectable threats including spyware, ransomware, banking trojans, harmful adware and potentially unwanted apps.

• Scan installed apps and saved files for malware.
• Check a downloaded APK before installing it.
• Scan an unfamiliar saved attachment before opening it.
• Investigate an app you do not recognize or unexpected pop-ups.
• Review detected threats before deciding what to remove.

A familiar name or icon alone cannot tell you whether an app is safe. Use the scan results together with the source of the download when deciding what to install.

Two engines, complementary analysis
Dual Engine combines known malware signatures with AI analysis. Signature checks help identify familiar threats. AI examines suspicious patterns to help assess new or disguised malware. Together, the approaches give you two ways to examine potentially harmful software.

Deep Detective adds heuristic checks for suspicious patterns. Protectstar AI CLOUD supports threat assessment and provides updated protection rules. These technologies support the scan when you check unfamiliar apps or downloads and review a detected risk.

From a detection to a clear next step
Open a finding to see which app or file is affected. Review the result, then delete a harmful file or follow Android's uninstall steps for a malicious app. You decide which action to take. Afterward, run another scan to look for remaining detectable threats.

Choose protection for your routine
