Boot into safe mode, find mscdmss.dll, rename it xxx.old and drag xxx.old to your desktop. Reboot into safe mode, right click and drag it into the recycle bin - click Move when prompted (you must drag and drop it - Not right click delete). Then right click on the recycle bin and empty it. That will remove the DLL but you should run NAV again. This Trojan is a monster and you might need to edit the registry to completely remove it. Go here: http://www.sophos.com/virusinfo/analyses/trojagentco.HTML - click Advanced for the information you will need to manually remove the Trojan. Hope this helps.

So don't worry if you can't find the file afterwards anymore - HijackThis already deleted it. But it's always a good idea to doublecheck.Please make sure you don't delete "similar looking" files as they may be legitimate.In case when you're in doubt or it didn't solve your problem, please start a NEW thread in the HijackThisforum with your HijackThislog.FYI... Ad-Aware removes this pest as well. So make sure you have the latest updates.
