Antivirus scan has been running for hours and won't finish

Antivirus scans take time because they check every file on your computer. A full scan can take 2 to 8 hours if you have lots of files. Your computer will be slow while it's running.

When your antivirus runs a full scan, it reads through every file and folder on your drive. The bigger your drive and the more files you have, the longer it takes. Your computer runs slower during a scan because the hard drive is working hard and your processor is busy checking files. This is normal.
