Can't open Anti-rooktkit to remove infection


Recommended Posts

I believe that my explorer.exe has been compromised by a new version of Poweliks, every time I start up my computer after a few moments a large number of comhost and windows presentation processes show up in my process list and cause my CPU usage to skyrocket from 5% to 80%-99%. In my attempts to remove the malware I booted my computer in safe mode and found with some tinkering that the problems only happen when i run explorer.exe and connect to the internet. Ontop of this i have also noticed briefly upon shutting down my computer that advertisements will show up as the computer turns off, likely running in the background the entire time. At this time i believe that explorer.exe is the only compromised process as it is the only one that triggers the other programs.

 

I decided to compare my computer's symptoms with reported malware and i think that Trojan.Poweliks is the most likely culprit. I decided to try and run avast, i found that avast refuses to open. So I went and downloaded the installer for Malwarebytes and found that upon running the installer it would simply refuse to start the installation process, no error code or anything, it just wouldn't run. Next I looked on the forums to try and figure out how to get MBAM to install, found a topic saying that chameleon would work, it didn't. After that i tried getting ADW cleaner, it ran just fine but couldn't detect any problems, should've figured as much in hindsight as this is a rootkit infection.

 

Having exhausted these options i found Malwarebytes Anti-Rootkit BETA and decided it was worth a shot, like with MBAM, MBAR wouldn't run.

 

 

So here i am hoping that someone can help me finally get rid of this thing, it's been on my computer since yesterday and i just want it gone.

 

Thank you for taking the time to help

I have not got a clue what drwebfixit is??

 

Download TDSSKiller and save it to your Desktop.

Make sure TDSSKiller.exe  is on the Desktop itself, not within a folder on the desktop.

Go to Start > Run (Or you can hold down your Windows key and press R) and copy and paste the following into the text field. (make sure you include the quote marks) Then press OK.

"%userprofile%\Desktop\TDSSKiller.exe" -l C:\TDSSKiller.txt

If it says "Hidden service detected" DO NOT type anything in. Just press Enter on your keyboard to not do anything to the file.
If Malicious objects are found, do NOT select Delete or Cure. Change the action to Skip, When it is done, a log file should be created on your C: drive called "TDSSKiller.txt" please copy and paste the contents of that file here.

Download RKill from here: http://www.bleepingcomputer.com/download/rkill/

There are three buttons to choose from with different names on, select the first one and save it to your desktop.

  • Double-click on the Rkill desktop icon to run the tool.
  • If using Vista or Windows 7/8, right-click on it and Run As Administrator.
  • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • A log pops up at the end of the run. This log file is located at C:\rkill.log. Please post this in your next reply.
  • If you do not see the black box flash on the screen delete the icon from the desktop and go back to the link for the download, select the next button and try to run the tool again, continue to repeat this process using the remaining buttons until the tool runs. You will find further links if you scroll down the page with other names, try them one at a time.
