We did some pretty thorough testing of Clamav, uvscan (McAfee) and sophie (Sophos) side by side on a mail gateway using amavisd.
Clamav is supposed to be good for filtering windows viruses out of email. I know Fastmail.fm dropped Kaspersky in favour of Clamav, they claimed the updates to be at least as good.
Clamav was *almost* as good as McAfee and definitely better than Sophos at detecting viruses. Clamav beat uvscan hands down on cpu usage and detection of Phishing scams.
Here's our latest stats - clamav is primary. uvscan only gets used if clamav doesn't detect a virus.
These statistics represent data from 2005-03-01 to yesterday Total detections - 7369 Total phishing scams - 7080 Total viruses - 289 Total McAfee - 23 Total ClamAV - 266
The last two lines are *unique* detections. Basically what it means is that clamav missed 23 viruses that uvscan subsequently caught. So clamav has a 92.04% virus detection rate so far for the month. (Updates are fetched and installed automatically for both scanners.)
When I was keeping separate stats on each, clamav ran about a half a percent behind uvscan and sophie *never* had an independent detection. It also had a much lower detection rate. (E.g. clamav 94.6, uvscan 95.3, sophie 91.8)
