My son's desktop computer, running XP, which he uses for both school work and gaming, has been infected by a number of trojans/rootkits including tdlcmd.dll and alureon. I've tried a number of approaches to clear these infestations, including MacAfee, Stinger, Avast, Windows Defender, MalwareBytes, etc. Initially, many of these programs would detect an infected file and quarantine or delete it, but the system would reinfect on startup. Now all of these programs hang on a full disk scan on Tdlcmd.dll in the Windows/system32 folder. The scan gets to that point, and the program freezes, requiring a reboot. Also, Windows freezes if I navigate to that folder and click on the file icon. I'm hoping that ComboFix can clear this mess up. Otherwise I will reluctantly wipe the hard drive and rebuild.
