The content rating is Everyone, and the package ID is com.gridinsoft.trojanscanner. The APK is 6.1 MB, light for a security tool, and it needs Android 6.0 or newer.
Anti Spy, pre-install scans and cloud checks
Anti Spy looks for apps that may watch your messages, microphone or location, including ones hidden from the app screen. You can scan a file from a website, a chat or a shared download before installing it. Apps already on the phone can be checked too, and new or updated apps are scanned automatically.
Detection runs on Gridinsoft technology, with optional cloud checks as a second source when a download looks suspicious. Local scans work without an account, and app files stay on the device even when cloud checks are added. Results show what was found and why it matters, and scan history helps you decide which apps to remove.
Scheduled scans and maintenance since 2017
Scans and threat-database updates can be scheduled, so checks happen without you starting them. The app first appeared on June 7, 2017, and the current version, 1.5.1.0, was updated on October 27, 2026. Nearly a decade of releases suggests ongoing upkeep.
