Hello. Just now on our Windows 7 computer, the orange progess light has been on for a while, even when no programs are up. In addition, Internet Explorer 8 is running slower than usual. A little bit ago, it wouldn't even come up. I turned off then turned on the router, which seemed to help, but it's still slow. Could these two events be connected? Could this be evidence of a virus and how could I deal with this? Thanks.
