McAfee downloaded the update automatically, told me i needed to reboot, and so I did. Now the computer is acting like I've got my full 1gig of RAM on second and a mere 5mb the next. Even as I'm typing its all stop/start/stop/start. When I try to scroll through a windows explorer window, within the same folder even, there is a significant lag between when I tell the computer to do what I want, and when it does it. I am currently running a Spybot scan. What else can I or should I do? Thanks again!
