Avast Mobile Security checks installed Android apps, opened web links, Wi-Fi conditions and selected files. Separate controls can gate chosen apps and place imported photos in encrypted storage. Avast Mobile Security works through permissions that Android grants. It cannot uninstall a system app that Android protects or keep every component active after the operating system removes a required permission.
One scan does not exercise every protection component
Scan now examines installed apps and documented changes to default device settings. Avast Mobile Security also checks a newly installed app when it first runs. An Avast Mobile Security scan result can open the documented false-positive report path when the user believes Avast classified an item incorrectly.
Web Guard handles another object. It uses Accessibility access to inspect opened URLs and display a warning or block. Android power management can disable that service while the Avast icon remains installed. Scan now may still work in that state even though Web Guard no longer checks links.
Scan Wi-Fi checks the connection, router and encryption conditions and can measure transfer throughput. Avast Mobile Security can request location access before it reads Wi-Fi network details. Without that permission, the network check cannot read the required details.
App Lock relies on Android permissions
App Lock places a PIN or pattern gate over selected apps. Supported devices can use a fingerprint instead. Usage Access tells Avast Mobile Security which app occupies the foreground, and Appear on Top lets it draw the authentication screen. Accessibility can also affect the protection path. Missing one permission can leave App Lock inactive while malware scanning continues.
Unlocking one protected app starts a shared timeout during which other protected apps remain accessible. Turning the screen off restores the gate immediately. App Lock therefore does not promise a new challenge for each app opened during that interval.
The Forgot PIN path depends on the Google account chosen during App Lock setup. The user must still sign in to that account before creating a replacement PIN. An account that was never linked cannot authorize the documented recovery route.
Detection and removal can become separate jobs
A hostile app can block normal removal while it holds Accessibility or device-administrator privileges. The documented workflow revokes those controls before uninstalling the app. Safe Mode is another path when the normal Android session still blocks removal.
A user-installed security app cannot uninstall system-level malware that Android protects. Avast Mobile Security’s documented options then move outside an ordinary scan: disable the app where Android permits it or use the device’s recovery path. A factory reset is a destructive recovery action, not an automatic result of Scan now.
Photo Vault is encrypted storage, not another backup
Photo Vault imports and hides selected photos inside protected storage. All Files access lets the component read and modify the chosen material. If the user removes the original photo and later deletes the vault item from trash, the documented workflow leaves no ordinary copy to recover.
The persistent notification helps Android keep background components available. It does not mean that a scan is currently running. Suppressing the background behavior can reduce the visible notification while making those continuous components easier for Android to stop.
