I've followed Symantec's removal instructions (http://www.symantec.com/avcenter/venc/data/backdoor.colfusion.html) but there are always at least 5 dlls which Norton (or the other apps I've tried) cannot remove.

Also, I always get winsock.scr and dxsetu.exe errors at startup, followed by "Exception EInOut Error in module dxsetu.exe at 000056F2 I/O error 32". ope1C3.exe and ope1C4.exe also try to connect to the internet (I find this files very suspicious). And I have an unusual amount of processes running (like 10 cmd.exe)..

Exactly the same problem here - I managed to delete the DLLs in Safe Mode, but the dxsetu.exe keeps on appearing in the registry, even after deletes.
The winsock.scr errors are probably the Trojan trying to mess with the antivirus.

I don't know if my situation is completely similar to keesjansma3 but I've tried the HijackThis thing to fix the dxsetu.exe entry. But after rebooting I can't find the file anywhere and if I run HijackThis the dxsetu entry is there again. I've also tried running APM but I can't find any of the trojan's dlls listed.

Problem is virtually the same - Hijackthis finds it, but I CANNOT FIND THE DXSETU.EXE file, even though registry entries & Hijackthis point to a F:\WINDOWS\dxsetu.exe location.

I have enclosed my hijackthis log

I also had this problem, but Dav555 very kindly provided this fix:

Make sure you turn off system restore first, Go into control panel, system, system restore tab and check\uncheck the system restore box.

you should fixed the following problems with HijackThis
F0 - system.ini: Shell=Explorer.exe winsock.scr
F2 - REG:system.ini: Shell=Explorer.exe winsock.scr
O4 - HKLM\..\Run: [dxset.exe] C:\WINDOWS\dxsetu.exe

then delete the following files with GiPo@FileUtilities (Move on boot)
(Remember to go into explorer, folder options, view and uncheck "hide protected operating system files" otherwise you'll spend forever and a day looking for things that aren't showing themselves, like I did!!!!!)


I think these locations are right, the above files are either in c:\windows or c:\windows\system32

Reboot, then do a full system scan with your anti-virus program, this will pick up all the affected files and should delete\quarantine them.

wot does the above line " then delete the following files with GiPo@FileUtilities (Move on boot) " wots gipo ? and what is move on boot mean ? sorry to be A PAIN!

Use Task Manager to terminate the Cold.Fusion process.
Delete the original Cold.Fusion file and folders.
Delete the system registry key parameters
Update your antivirus databases or buy antivirus software and perform a full scan of the computer.
