Scan Speeds for FREE AntiVirus Software
The scanning speeds shown below are for default settings
for each free antivirus program
. Since the default
settings for each program are quite different, the testing below doesn't necessarily indicate which free antivirus program has the fastest virus scanner. However, since most users don't alter the default settings, it's useful to see how fast each program is in default
Scan speeds were found for the first/initial scan after installation (a 1.0 GB set of 3000 files was scanned - which included Windows system files, media files, and other files commonly found on a computer system). Subsequent scans are generally faster than the initial scan speeds shown below. (See our Free Antivirus Performance Tests
where we also tested Subsequent Scan Speeds.
