Do a malware check with a few malware scan programs. You need to use all programs because each detects different malware.

I have the same problem, but I've also ran 4 different scans all from different anti-malware/spyware programs and its still happening.

Using Windows 7 and I have AVG, Malwarebytes, Ad-Aware, and the general Wall that's already on my computer.
