Hello:

Thank you for taking the time to review my logs.

I was infected with Malware defense and what I believe was a TDSS rootkit. I ran GMER, then combo fix. I've attached my before and after GMER logs. I can post my combofix log if requested. Can anyone verify that I have removed the rootkit completely?

My symptoms were:

Malware defense popups.
Redirected google searches.
nt.dll crashes
googleupdater crashes ???
GMER found rootkit.
IE trying to go to networkreferences.cn but IE not loaded (discovered in AVG install tool that shows "open" IE page titles)
Also, after telling IE to be in offline mode, kept bugging me to go back to online mode to open a page (that I didn't request)

Current symptoms:
Things that make me wonder. :(
AVG spinning all 4 cores. (I uninstalled and reinstalled since I had installed it when the computer was infected with rootkit, no more spinning.)
Delay in loading up windows explorer.
Every delay must be a rootkit. :( Running 4gb RAM on i7.


I also reset firefox profiles... erased addons, etc. Is there a way to do this with IE6?


Here is my BEFORE GMER log:
