I am using windows xp. Suddenly, the CPU usage is close to 100% and extremely slow. I already updated and did a scan using malwarebytes and superantispyware. I also ran CCleaner and also scanned the registry. Usually these steps fix all problems, but now these programs did not find any problem, so I do not know why the computer is very slow suddenly.

I just ran hijackthis and got the following logfile:

Do you have any ideas what the problem could be and how to fix it? Do I have a virus?

Thank you. To clarify the problem, I found that whenever I ran "superantispyware" the cpu usage would go to 100% and it would take a very long time for the program to open, or sometimes it would never open. Now the problem went away, I think I fixed it by uninstalling "superantispyware" and downloading and installing it again. But could a bad rootkit have already infected my computer and still be there without me knowing it?

I will do what you said and post the log here.
