my computer freezes most of the time when I try to click on something from one email to something on their site page.  When trying to exit, page turns white with X button to exit but does not work, have to reboot most times to get out and back up again.  Do I have a virus? Or is there an answer? I have Outlook Express.

Try here for possible solution.
