I had a problem with my computer (Deminsion 2400) and had it solved by one of Dell's Moderator. He said to use MicroTend HouseCall and I did. It fixed the problem. I did have a virus. He also said to run it at least once a week. So far so good. Now it seems that I can't open it. I get a message that says "unable to run housecall. Because this website is not authourized to hose HouseCall. Does anyone know what that is about? I had saved it to favorites and each time went there to use it. The only thing that has been added is Google Toolbar. What do I try? Dana
