Who has eight pc's ???? I am gealous. I only have 5 at the moment..This is really bad luck getting them all infected... I used to use AVG but I upgraded to Avast Pro...I have not had a worry since...I have tried most of them over the years...I tried AVG for over a year but things kept sneeking in...It wasn't obvious though...Now I have avast on my computers the alarm bells are ringing all the time...AVG gave me no such warnings. Even the paid version doesn't stack up to Avast Pro.
