I recommend following this http://forums.avg.com/ww-en/avg-forums?sec=thread&act=show&id=228683 article.
Let me know how it goes.
My AVG works OK but there is an annoying glitch, which is something new(I have been using AVG for some years).
After a few minutes of getting on line a message comes on to ask to restart the computer to get the security in place.
Not the exact words of the message but it sums up the essential issue.
Is it normal or there is something I can do about it.
