[ihatevirus's]

Okay to keep things simple i downloaded a trojan from a keygen which renamed my explorer.exe to explorer.ex_ after learning how to get to it and rename it back to explorer.exe and placing it back in the WINDOWS folder things seemed fine.. I did a virus scan through a online scanner and it couldn't delete a trojan i forgot its name unfortunately, anyway this trojan does not allow me to install avg, luckily i had malwarebytes anti-malware already installed doing a full system scan with it i received error code: 721 (0,7). Also while joining this forum so i could post this, i looked at the screen and about after scanning 15000 more files i received another "Error code: 722 (0,7)" is this the trojan preventing itself from being found?!
