I get this weird popup. It is not related to me surfing the web because it can popup when I don't have a browser open. I have used SpyBot and SpywareBlaster and everything looks good on that end. I am unable to close this, I have to crtl.alt.delete to end it. I tried viewing source to gather some info but I am unable to get a right-click menu. I think I recall finding some article about getting a popup like this one in reference to Internet SignUp so I am not sure if that is what this is related to.
