Protectstar Antivirus AI
Protectstar Antivirus AI is an Android antivirus app listing real-time and ransomware protection. Its free plan costs nothing, has no expiration date, and includes manual AI scanning with a dual engine, anti-ransomware protection, and quarantine and restore. Paid plans are listed at €8.95 a year for PRO and €13.95 a year for GOV; each standard license covers one device. The listed device limit is one. Protectstar was founded in 2004 and is headquartered in Sarasota, Florida, USA. Additional technical details list disk wiping, SSD and removable-media support, and erasure reports with basic verification. Bootable media is not supported. The product information identifies Android as the supported platform, but also lists a mac-only coverage scope, so those platform details do not align.
