Notes: Scan Times shown below are for default settings for each Antivirus program. 70 GB of used hard-drive space was scanned with each virus scanner. Since the default settings on each antivirus program are quite different, the testing below doesn't indicate which Antivirus program is the fastest, however, since most users don't alter the default settings it's useful to see how fast each is in default mode.
