Doesn't sound like malware but since this is the malware forum, let's rule it out:
Download :
ADWCleaner to your desktop. Make sure you get the correct Download button. Sometimes the ads on BleepingComputer will mimic the real Download button which should say: Download Now @BleepingComputer

Close all programs, pause your anti-virus and run AdwCleaner (Vista or Win 7 => right click and Run As Administrator).
Click on Scan and follow the prompts. Let it run unhindered. When done, click on the Clean button, and follow the prompts. Allow the system to reboot. You will then be presented with the report. Copy & Paste this report on your next reply.
The report will be saved in the C:\AdwCleaner folder.
