Virus?

[mgs29035]

It seems to be the worst when Internet Explorer is open. All I really do on this computer is play poker, surf the net and check email. The application that doesn't work most frequently and needs a restart is Outlook Express.

When I go in task manager, there are no programs open and the cpu usage seems to be unusually high.

After a fresh reboot, it's not that bad, but after about a half hour or so, it gets worse.
