Hi again. I was just watching videos on youtube when IE closed down and the desktop turned black. I ran Security Essentials and came up with something called Pum. Hijack.Start Menu. I removed a couple with Se and Malwarebytes, but it still keeps coming back. I'm not exactly sure hwat to do about it, so I came here. I'm running Windows 7 hime Premium on a stock Dell XPS 8300. Thanks in advance.
