I suffered with McAfee for years and there were times I thought it WAS a virus. I also hear bad things about Norton AV (gobbles up a big chunk of your CPU resources)so I am not sure there is such a thing as a "good" anti virus program.
The real problem is windoze itself. It is so vulnerable to evil doers that the cure is almost as bad as the disease. (think Chemo therapy).
My wife likes Malware Bytes.
