You are most likely receiving a bogus infection warning, or a fake alert, from a Rogue security program.
Try the following:
Get into Windows 7 >Safe Mode with Networking<
Next, download RKill:
[If the file does not download, paste the following, >without the brackets<, in the address bar of your browser:
Save to the Desktop.
Vista/Windows 7 users right-click and select: Run As Administrator.
A black DOS box briefly flashes and then disappears. This indicates the tool ran successfully.
If not, delete the Rkill file, then download and use another Rkill file:
If it still does not work, repeat the process and attempt to use one of the remaining versions until the tool runs.
Note: You may need to make repeated attempts to use Rkill before it runs, as some malware variants try to block it.
Once the tool completes its work, the window closes and a log is displayed.
>>Please post the contents of the log in your reply.<<
Note: If you get an alert that RKill is infected, ignore it. The alert is a fake warning given by the rogue software which attempts to terminate tools that try to remove it. Leave the alert on the screen and run RKill again. By not closing the alert, it sometimes allows you to bypass the malware's attempt to protect itself so that RKill can perform its routine.
Without a reboot, download Malwarebytes’ Anti-Malware (black button with green and white icon) Save to the Desktop:
Double-click mbam-setup.exe and follow the prompts to install the program. (For Vista or Windows 7, select: Run as Administrator)
Run Malwarfebytes’ AntiMalware and update the program.
Once updated, select Perform Full Scan and click the scan button.
When the scan finishes, click OK in the message box, and you will see the results of the scan.
Click the Remove Selected button to get rid of the malware.
When Malwarebytes finishes, you may be prompted to reboot. If so, reboot.
>>Please post the Malwarebytes log in your reply so we can see where we are at, and plan any additional removal strategy, if necessary.<<
