I have AVG 7, professional version, and it was less than $40 for two years fulltime coverage. But as you said, Alicat, it doesn't deal with embedded files. I have three recurring ones that I have not been able to isolate or 'heal,' so hopefully, they aren't really bothersome? They are all three trojans, and two are located in my daughter's PWS file. So far, I can't detect any real problems on my PC.
Raph, I think Norton used to be good, but has slipped in the past three or four years. None of the programmers or web designers I know use it anymore. Everyone seems to be happy with the standard free AVG. I only upgraded to 7.0 prof version because 6.0 didn't do anything to those viruses, and so far, the paid-for version doesn't either !!!
