Nortons can detect the virus, but never really cleans it out. Invasive on the OS also.
Avg is ok, although still allowed trojans that it couldn’t get rid of.

Avast is the best that I have found so far. It actually gets rid of 99% of viruses that it finds, and they don’t come back. It also works well with windows shield. I have both at the same time. I have found only one virus it couldn’t repair, that I had to delete the file.
