When I turned on my computer this morning, I got a window that said (paraphrasing): "ActiveShield could not be installed due to insufficient space. Please close some open programs and try again." I have over 90GB available on my HD so I don't think space is the issue, and I don't have any programs automatically start at start-up except McAfee. None of the windows I had open were showing up in the taskbar, and after restarting the taskbar is now gone completely. I also can't pull up my Start menu at all (even using the keyboard button). Anyone know what's going on? I'm on a Dell PC running Windows XP. Thanks.
