Infected with BDS/Backdoor.Gen

Today my friend was trying to speed up my computer, and we noticed that a lot of CPU was being eaten up that shouldn't be, but no programs in my Task Manager showed why. So we ran a virus scan in MalwareBytes and Avira Anti-Virus, and got a few hits, but we're mostly concerned about the things Avira found in it's scan.

The results found two BDS/Backdoor.Gen files, and we quickly Quarantined them, and my friend I mentioned earlier recommended I check with you all to make sure my PC was no longer infected.

Thanks.

EDIT: I uninstalled GIMP 2, and I installed Paint.NET.
