Quote of the Day - If computers get too powerful, we can organize them into a committee -- that will do them in.
So, you already use an anti-virus product, and you pay dearly for it each year. Symantec, McAfee and others are all out there. A little late but with a lower and broader price tag, Microsoft offers OneCare for up to three computers for under $50.00.
