First time scan with AVG Anti-Virus Free finds two infected dll's in "C:\Program Files\Malwarebytes' Anti-Malware\mbamnet.dll";"Trojaner: BackDoor.Generic13.YXN";"Infiziert" "";"C:\Program Files\Malwarebytes' Anti-Malware\mbamcore.dll";"Trojaner: BackDoor.Generic13.YXM";"Infiziert" on a brand new system. Scans with Malewarebyte's Anti-Maleware, AdAware & Spybot Search&Destroy couldn't find those. As i guess deleting those files would damage you'r software, but if they are actually are infected ... could you somehow check if the files are false positves?
