Background scan is an automatic scan mode of Kaspersky Internet Security that does not display notifications. This scan requires fewer computer resources than other types of scans (for example, Full Scan). When in this mode, Kaspersky Internet Security scans the system memory, system volumes, boot sectors and startup objects, and searches for rootkits.

A background scan is started in the following cases:

  • After the anti-virus databases are updated.
  • Thirty minutes after Kaspersky Internet Security launch.
  • Every six hours.
  • If the computer remains idle for five or more minutes (after the screen saver is started).

A background scan is interrupted when any of the following conditions is met:

  • The computer becomes active again.
  • If an Idle Scan has not been performed for more than ten days, then the scan will not be interrupted and allowed to finish.
  • The computer (laptop) switches to battery mode.

When running a background scan, Kaspersky Internet Security does not scan files whose contents are located in OneDrive cloud storage.

To enable or disable a background scan:

  1. Open the main application window.
  2. Click the Scan button.

    The Scan window opens.

  3. In the Scan window, click the Settings 2019.png icon in the Background scan block.

    The Background scan settings window opens.

  4. In the Background scan settings window, switch the toggle to On or Off.
