Also, if you still have difficulties after following the comments above, try downloading ComboFix to another machine, then into a USB memory stick (or equivalent). Rename it and then connect it to the infected machine.

Hey Install AVG ROOTKIT http://www.softpedia.com/g
and run the scan....this will sure help you :)
as advised above Combofix should be able handle this infection, if this did not work for some reason, I found the below method posted on Malwarebytes forum straightforward and effecient at cleaning this particular infection, the idea is to allow the user to remove the main rootkit component using a tool like RootRepeal , then allow Malwarebytes antimalware to clean the leftovers, this routine has proven the only way to go when running Combofix is not possible,e.g. Vista problems or Windows 2003 server ,etc..

Note:
Hi rolfg :... well i have faced that TDSS trojan problem on my computer..
I have malwarebytes also installed on my computer..but it doesn't remove the virus completly..as soon as you reboot your computer the virus will com again...so that is why i have given the perfect solution of installing AVG ROOTKIT...which completly removed that virus.. from the computer ...
For AVG ROOTKIT go here http://www.softpedia.com/g
That's good, and you'll see that the ComboFix log has several "Other Deletions" of infection(s).
Although perhaps not a problem, you may well have some Spyware remaining .. for example, this entry>>
c:\program files\Lx_cats
It's in the "Find3M Report". Assume you are running a Lexmark product?
Details>http://homerun-netw
You could try downloading, then updating Malwarebytes' Anti-Malware (already suggested by Admin3k):
http://www.malwarebytes.or
Superantispyware:

There's also a-squared Free:

Have quickly studied the remainder of the Combo log & it may well be okay .. have to logoff for the night ... perhaps IndiGenus would like to comment more .. if not, i'll be around at first light ..
There are some things that should still be dealt with here. The sysaudio.sys infection is covered nicely by Miekiemoes in her blog.

1. Open Notepad.
2. Now copy/paste the text between the lines below into the Notepad window:

3. Save the above as CFScript.txt on your desktop.
4. Then drag the CFScript.txt into ComboFix.exe. This will start ComboFix again.
5. After reboot, (in case it asks to reboot), please upload the following reports/logs.
-Combofix.txt
Once again it appears clean, at least the sysaudio.sys infection seems to be gone, but maybe Indigenus will have further comments.
When you have finally finished with ComboFix, you can uninstall it as follows >
Start > Run > then type "ComboFix /u" (with no quotes, and space between x and / )
Then hit enter. This will uninstall ComboFix, reset your clock settings, re-hide system hidden files, re-hide the file extensions and reset System Restore.

Delete the version of combofix you have now, then renaming combofix to combo-fix.exe, before downloading it. Try again and that should allow it to run. Attach the log, there may be more.
