I went to download at computer game, and AVG came up saying virus found. IDP.Program.D1B0A5C0 was the threat name. I bought the game of eBay. However the game was in its original packaging. I had bought the game once before but the disk broke because of my dog. The wrapping looked similar and everything was OK, until I tried to use it. What is wrong? What should I do? I have a 14 return period, should I return it now?
