Everyone is entitled to their opinion and I respect that. I have been using AVG for over three years on my systems (5) at home and have not had a single problem. I believe using good judgement as to what you do, where you go on the web is just as important. Not everything protects 100% and I don't care what product it is. I have seen them all at some point on my client's PC's during the years become infected. Enough said, try the AVG see how it works and hope you get your system back up.
