[Sailing Mishap!]

I've read different things about the DrW Postmortem Debugger, some say it's a virus and I've read also that it's just part of the system. Well, I think mine's a virus, as frequently my IE freezes/slows, as does my AIM. My Firefox won't even work. And sometimes my computer reboots, although I've never been around when it does it (I'll go to bed and then in the morning, it's restarted).

Here's my HiJackThis log:
