Malwarebytes Premium blocks IP's, svchost.exe run by gpsvc overrruns TCP connections to 80, previous redirects, BSOD, and resets

Here's the background:

After doing a thorough cleaning of MBAM, ESET, & MSSE, I started seeing the Blocked IP messages, and it was obvious from a "netstat -ano" that the offending executable was svchost.exe, which was also growing in RAM until the entire machine would either become completely unresponsive, BSOD, or just reset. So in an effort to isolate the problem, I followed "Getting Started with SVCHOST.EXE Troubleshooting" http://blogs.technet...leshooting.aspx , and found through isolating the services to their own svchost.exe that the offending service was gpsvc .

gpsvc has protected permissions in regedit, and I'm hesitant to mess with it. The machine was previously a domain member, but now is stand-alone and the problem persists, so if the problem resides there, it's local.

Disabling the adapter connecting to the Internet seems to be the best way to halt the virus activity, and prevent crashing. Using the TCP/IP tab of "Process Explorer" you can watch the svchost with the gpsvc service grow and start launching all the tcp connections a few seconds after an Internet connection can be established.

So what is this evil, and how can we cast it out forever?

Since I was experiencing the exact issues as "piggyigg", I went rogue and followed Maurice Naggar's instructions here:

http://forums.malwar...ndpost&p=535809

Even though I didn't think it was going to work, I ran Combofix, RogueKiller(crashed), TDSSKiller, & GooredFix

The most significant I believe was Combofix & TDSSKiller.

svchost.exe is now clean. I set the service types back to "share" and all is well.

One of the items I noted Combofix delete was an ini file for the Intel wireless on this laptop. Not sure if that was triggerring the problem or not -- just glad it's over now.

TDSSKiller also found what looked like a hidden virtual harddisk.

Thanks to Maurice!

Please print or save this topic: it will make it easier for you to follow the instructions and complete all of the necessary steps.

-------------

Please download to your Desktop:

  • TDSSKiller.zip from here and extract it (right click on it => "Extract here").

>>> TDSSKiller: Double-click on TDSSKiller.exe to run the application.

  • Click on the Start Scan button and wait for the scan and disinfection process to be over.
