My 2 cents...
Was using an AV program recommended to me by a Navy LCDR with a masters in computer tech. He said Clam Win was great so downloaded it as freeware. Never a problem and it caught stuff every so often, and I was always able to get rid of the nasties.
Reading the posts above, no one even mentioned Clam Win so I figured maybe I’d better upgrade to Kaspersky and pay for some “real” protection.
Scanned my entire system with the Kaspersky AV and it found nothing as well. No worries. But it does have better options and will use it until license expires in a year.
Spybot runs on my system as well.
I didnt know Clam AV had a Windows version of course it might not be the same as I am thinking of, if it is it would be a good choice. The Clam I am thinking of is used on Unix systems wonder if it is the same.
