Antivirus AI - Virus Scanner

Antivirus AI by Protectstar is an antivirus app and virus scanner for Android. Check your phone's apps, files and APK downloads for malware, spyware and other threats. See the results and take action on detected risks, with no ads getting in the way of your scan.

Start with a free manual virus scan. PRO and GOV provide real-time protection in the background and scheduled scans for continued monitoring.

Independently tested protection
Antivirus AI received AV-TEST certification in 2023, 2024 and 2025. Its app security has also been assessed under DEKRA MASA L1. Antivirus testing examines protection, performance and usability; MASA evaluates defined security requirements for the app itself.

Check downloads before installing
An APK received in a message or found on a website deserves a closer look. Scan the file before installation and review any findings. Antivirus AI also checks installed apps, helping you review the software already on the phone you use for banking, shopping, communication and work.

• Start an on-demand antivirus scan.
• Check installed apps and downloaded APK files.
• Detect malware, spyware, ransomware and banking trojans.
• Identify harmful adware and potentially unwanted apps.
• Review detected threats and follow the available removal steps.

Malware removal you can follow
Finding a threat is only part of the task. Antivirus AI shows the result so you can decide what to do next. Remove a harmful file or use Android's uninstall process for a detected malicious app. Available quarantine options depend on your edition and the type of finding. Run another scan after taking action to check for remaining detectable threats.

Two engines for layered detection
Dual Engine brings signature-based scanning and AI analysis together. The signature engine recognises known malware, while pattern and behaviour analysis help assess unfamiliar or disguised threats. Your security scan can draw on both approaches instead of relying on a single detection method.

Deep Detective™ adds heuristic analysis. Protectstar AI CLOUD supports the assessment of threats and distribution of updated protection rules. The goal is to help you identify risks and respond with a practical next step, rather than leave you with an unexplained warning.

No ads or advertising trackers
Keep the focus on your phone's security. Antivirus AI does not sell personal data. Technical app, file and device information may be processed for security features, as described in the privacy policy and the Google Play Data safety section.

Useful for everyday checks
Run a malware scan after downloading software, when you discover an unfamiliar app or when unexpected pop-ups appear. Increased mobile data use or battery drain alone does not prove an infection. Use scan results to investigate detectable threats, and keep Android and your apps updated.

Start free, choose more protection
FREE includes manual antivirus scans without a subscription. PRO adds real-time malware protection and scheduled scans. GOV includes PRO features plus additional security options for more demanding needs. The in-app comparison explains which features are included before you upgrade.

Paid features require a purchase. Prices, billing periods and any trial conditions are shown before you confirm. You can manage subscriptions purchased through Google Play in Google Play.

Virus removal, not storage cleaning
Looking for a virus cleaner? Antivirus AI helps remove detected malware. It does not clear junk files or boost RAM. No scan can guarantee detection of every threat, so combine it with careful downloads and regular updates.
