    • C:\ProgramData\Kaspersky Lab\AVP13\Bases (for OS Windows Vista/7)
  4. Update the program anti-virus databases.
  5. When the update is over, exit from the application. To do so, right-click the application icon in the Taskbar notification area in the right lower corner of the screen and select Exit from the menu.
