Hi! I just registered on here. Ok, so my problem is this trojan that won't get removed from my PC. I have already used Norton, AVG, Spybot, AdAware and SuperANTISpyware to get rid of it and yet I have failed. Of course, during the process those programs removed other viruses, and so far it seems that this "Trojan.Duntek" is the only remaining one. It is encripted or stored in a dll file, it's called extdat.dll or something alike, Norton detects it... but it can't delete it, not even in safe mode... I have tried deleting it manually, it doesn't work either, it says that the file is on use. So, it seems that the file gets active when Windows starts, making it a real pain. Also, I can't use the TaskManager it seems that the trojan blocked it, so I can't point which program uses it in order to disable the file. So, I searched on the web for removal instructions, but they are always the same: run an anti-virus, anti-spyware, do the same under safe mode and it should be done. Well, it doesn't work. I have even looked on symantec page for virus removal instructions and it says to delete all infected files first, but that's the problem, not even in safe mode can't delete those files. Erasing the registry values seems to be useless as well (I guess that the dll file just rewrites them again)... And well... that's all... I don't know what to do anymore... Symantec says it's a low risk trojan, but I guess it really isn't because if I open Internet Explorer it opens other windows as well... So, well, what should I do... or what should I use... I really need help for this. Thanks!!
