AVG is, I think, a blocker. It blocks new threats and I dont think it can erase any virus. But im glad I have AVG. If you're already infected, I suggesr MBAM, Combofix, Super Antispyware and an online kaspersky scan in order. The website I gave will probably give you similar instructions.
But be warn. YOU MUST USE PROPERLY TITLE AND PROPER GRAMMER. lol
