BleepingComputer.com: Help removing Malware from my PC

Hi guys,



I am in trouble. Yesterday i downloaded a .exe file from a web-site and ran it after scanning with MSE (it didn't flag the file as dangerous)

As soon as i ran the file, the file got deleted itself and something suspicious happened (i think it downloaded something from the Internet or made some registry changes). After that my Security center and MSE got diasbled on its own. Now i am not able to start MSE and Security cen ter. My IE9 is also behaving strangely taking me to redirected sites sometimes on its own.



Here's is the report from VirusTotal of the file i downloaded :-

I ran MalwareBytes and Microsoft Safety scanner and Spybot but with no benefits. SpyBot detected some trojan registry entries which i deleted but problem still remains. Microsoft Safety scanner detected 1 threat which i removed but still no solution.

Also i downloaded G-Data trial version and installed it. Whenever i started IE9 it used to say run32.dll is showing suspicious behaviour and browser does have malware, but G-data didn't had a fix for it..Now i have uninstalled G-data



Please help me. I have not been able to use my PC since 2 days..



Thanks

Ankit

Please download GMER from one of the following locations and save it to your desktop:

• Main Mirror
  This version will download a randomly named file (Recommended)
  
• Zipped Mirror
  This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.

• Disconnect from the Internet and close all running programs.
  
• Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  
• Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  
• Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.
  
  
  
  
• GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  
• If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  
• Now click the Scan button. If you see a rootkit warning window, click OK.
  
• When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  
• Click the Copy button and paste the results into your next reply.
  
• Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

IMPORTANT! If for some reason GMER refuses to run, try again.
If it still fails, try to UN-check "Devices" in right pane.
If still no joy, try to run it from Safe Mode.
