MD, et all, -

I'd also put in a big vote for Kaspersky Antivirus - changed over from Norton a month a go or so. It has better detection (found things Norton couldn't find) and I combine it with Malware bytes.

I'm not a windows expert by any means - I really don't want to invest additional cycles to do more than I do or know more than I already do. Our IT support team told me to move to Kaspersky and add Malware - that was good enough for me and I'm convinced it's better than Norton Anti-Virus.

My thought is though that on the virus side, it's probably ok to have multiple tools as I believe no one vendor can have 100% detection/fixes against everything rapidly.
