You may try the following fixes and check if that helps to get rid of the pop up.
Boot the computer in safe mode and check for the issue.
Some options, such as safe mode, start Windows in a limited state, where only the bare essentials are started. If a problem doesn't reappear when you start in safe mode, you can eliminate the default settings and basic device drivers and services as possible causes.
Follow this below provided link to start your computer in safe mode.http://windows.microsoft.com/en-US/wind ... -safe-mode
Place the computer in clean boot and check if the issue persists.
To help troubleshoot error messages and other issues, you can start Windows by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts.

Note: After troubleshooting, make sure to put the computer to start as usual as mentioned in Step 3 from the above provided KB article.
Method 2: I would also suggest you to scan your computer with Microsoft Safety Scanner, which would help us to get rid of viruses, spyware, and other malicious software.
The Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with your existing antivirus software.http://www.microsoft.com/security/scann ... fault.aspx
Note: The Microsoft Safety Scanner expires 10 days after being downloaded. To rerun a scan with the latest anti-malware definitions, download and run the Microsoft Safety Scanner again.
Important: While scanning the hard drive if any bad sectors are found, the scanner tries to repair that sector, any data available on that might be lost.
