Hello,
Recently, my AVG did not work, it would seem like if it was corrupted. I did not do anything, but recently when trying to play a game, it would not work. The developer told me that AVG would block the game from launching, and therefore I had to bypass the security system on that game. However, since my AVG did not work, I could not do this. After browsing for a while, I found out I can repair the program, but at around 40-50%, it would display an error message like on the title. I do not know what to do at this point. 
P.S: My Avg recently expired, but the program was corrupted way back.
