I have some really old machines and want to run a virus scan on them. They only have about 64mb RAM, 333Mhz processor, etc. I don't want a whole suite, just something light weight and effective.

For Windows 98 and upwards you could try Clamwin. Note that is does not do on-access scanning. You need to manually or schedule a scan of your drives.

Seconding the clamwin suggestion. I run it on some old p2 machines just fine. – Chris_K Aug 5 '09 at 15:22
I am going to use the portable version. it's only 6MB (27MB installed). – scottm Aug 5 '09 at 16:13

Personally, I vote for "Don't give the user Administrator rights", "Apply current security fixes", and "Don't run unnecessary services or software" for a low-impact anti-virus solution.

these aren't user computers, the owners only allow "system changes" rarely, and they don't run unnecessary software. – scottm Aug 5 '09 at 15:53

dr.web seems to be so.

4 i think – TiFFolk Aug 6 '09 at 9:04
indeed. Just checked the docs - both 4.44 and 5.0 should work just fine with 64 MB RAM – dmityugov Aug 6 '09 at 12:05
