Are you able to launch programs, or do you launch the infection instead of the desired program?
Try the following:
Save it to your Desktop.
Now, close all open programs.
For XP, simply double-click RogueKiller.exe
For Vista/Windows 7, right click the file and select: Run as Administrator
When prompted, type 1 and hit Enter.
An RKreport.txt should appear on your Desktop.
Note: If the program is blocked, do not hesitate to try several times. If it really does not work (it could happen), rename it to winlogon.exe
>>Please post the contents of the >RKreport.txt< in your reply.<<
We will take further action based on the results of this report.
