My current choice Antivir from Avira. Freeware.
It catches stuff that NIS didn't.
The problem with Antivirus products is that the best doesn't remain best for long. Things change with time. In the past I have used NIS, McAfee, Sophos, Kaspersky, AVG, Avast and don't know what else. There was a time I was a fan of AVG but that was brief. Then it was Avast for very long time. Now it is Avira.
