I had Mac a Big Fee for years and it was crap. I has viruses on my pc it could do nothing about but tell me it couldnt do anything. SO I tried the AVG Free 7.5 and it kicks Mac a Big Fee ass big time. I ran it with Mac a Big Fee 2008 and Mac a Big Fee 2008 did not detect the viruses my pc had but the free AVG did and it go rid of them as well. Dont waste money with Mac a Big Fee go AVG then if you like, it by the 8.x version, which is much better, and it cost less.
