If you cannot download the following file, the malware may be blocking the attempt. You need to download the file to a clean computer and then transfer it to the infected one using a USB flash drive, or external media (an external drive or a CD).
Please download exeHelper from one of these two places:
Save it to your USB drive, and then transfer it to the Desktop
Vista or Windows 7 users right click the downloaded file and select “Run as Administrator"
XP users, double-click on the downloaded file to run the program
A black window should pop up
Press any key to close, once the fix is completed.
>>Please post the contents of the exehelperlog.txt in your reply.<<
[It is created in the directory where you ran exeHelper, and should also open at the end of the scan.]
Next, see if you can download RogueKiller
Save it to your Desktop.
Close all open programs.
For Vista/Windows 7, right click the file and select: Run as Administrator
For Windows XP, double-click the downloaded file.
Note: If the program is getting blocked, do not hesitate to try running it several times. If it does not work at all, delete the previous download, download it again, and in the Save as prompt, File Name area, rename it: winlogon.exe
When prompted, type 1 and hit Enter.
An RKreport.txt should appear on your Desktop.
