The AVG free version was kind of slow (18 hours for a full scan of a 160 GB disk which is about 75% full) put it doesn't expire.
Not only does TrendMicro expire in 30 days but it thinks GoToMyPC is a virus and quarantined it. Without even asking or giving me a choice.
No real problems were found by either.
If I didn't have access to a McAfee site license (from work), I might use AVG, but there is no way that I would use TrendMicro.
Now to go back to the restore point and get back to McAfee.
