I personally like AVG. I'm too cheap to buy antivirus. I guess I'm one of these old school guys that remembers when they didn't charge you a subscription fee every year. I felt like if I bought it, I should not have to keep rebuying once a year. To me as well, some versions of like Norton and Mcafee seem like a drag on your system. I guess I try to keep backups, and I feel if something goes wrong, I'm competent enough to handle it. I would run that along with a firewall program. For AVG and what not, they actually have a paid version. I think they are supposed to have a good detection rate. Just do your research.
