Multiple Virus files infecting computer.

I seem to have the same issues with some viruses and trojans as several others here. However, when I try the fixes recommended I am unable to remove the virus file permanently. I am finding theddabb.dll, a file called lmtdcsij.dll igfxtray.exe, hkcmd.exe, igfxpers.exe as well as several instances of a name server entry in the registry for IP address 68.15.165.12. The computer keeps having multiple scteens pop up when using IE6 It would seem there should be a way to remove these files and the registry entries by manually editing the registry. However, all the solutions I am seeing require me to download several different programs like vundo and vundofix. and so far these have been ineffectual. can anybody help me with this?
