If there are any threats detected, Kaspersky will notify you. You can take the following actions to handle the threats : Disinfect(lets you work with the file), delete(completely remove the file) , Quarantine (moves the threat to kaspersky storage for removal or restoration at a later time)

STEP 4 : Take A Backup Of all important files and login to Windows

Take a backup of all the clean files using the Kaspersky Rescue disk for later use. Remove the USB drive and Restart your computer. Try to login to Windows. Even if you have successfully logged in, I strongly recommend that you take a backup, and completely reinstall Windows.
