Thanks everyone for the Strongvault answers. I agree that it is a virus; it was downloaded along with other spam-generating viral software such as Yontoo when I downloaded a clock app a few weeks ago. One day after downloading this software I started getting bombarded with 20-30 SPAMs a day, everything from free samples of Fabreze to ****. It also caused Internet Explorer to crash whenever I used it. I realized this about a week later and uninstalled all the unwanted software through the uninstall section in Control Panel (Windows 7). I uninstalled the Strongvault, but today when I opened Task Manager, I saw Strongvault was running in the background. I'm going to try the tips mentioned above and let you know how it comes out.
