You can start the following types of scans:
Kaspersky Internet Security scans the device's entire file system. A full scan helps protect your personal data and money, it detects and eliminates threats on your device (in installed apps and installation packages). A full scan also detects adware and apps that intruders may use to harm your device or exploit your personal data.
Kaspersky recommends you run a full scan of your device once a week to ensure your personal data is safe. If you do not want to start a scan manually, you may set up regular scanning:
Kaspersky Internet Security only scans installed apps. If you are using the free version, Kaspersky recommends you run a quick scan every time you install a new app.
If you do not want to start a scan manually, in the premium version, you may set up a scheduled scan of installed apps.
Due to technical limitations, the app cannot scan archives that are 4 GB or larger. The app skips these archives when scanning. The app does not notify you if such archives are skipped.
