I am personally partial to what used to be known as AVP (AntiVirus toolkit Pro) - its know known as Kaspersky Antivirus. However - its NOT free.

It is however very low in resource requirements - has a better capture rate than any other sftw on the market, has HOURLY updates (24/7) for new viruses (if you want it to update that often) and yes that means they release new definitions hourly. On average - a new threat is neutralized within 3 hours. In addition, its very customizable, rootkit and spyware effective, can do thread behavior monitoring and keeps an eye on registry edits as well.

Overall - its a really nice package. But like norton your doing a yearly subscription.

I have a machine I will try avast on - see what I think. Thanks for the heads up on it.
