About two months after purchasing their two year anti-virus protection service plan, AVG 2011, my computer ran increasingly slower. When I contacted tech support I was told that I would have to pay another $129 for them to clean it up. Finally got my computer back to normal using another anti virus program and uninstalled AVG. I have repeatedly requested a refund (even filed a complaint with BBB in MA) but AVG refuses to refund my money. If they can't provide the service as promised they should return everyone's money. Is there a class action law suit against AVG?
