Malware causing sugglish performance

[eason]

About two days ago my computer started to be very, very sluggish. The computer takes forever to startup and when I look in the task manager it says CPU usage is at around 50%, though no program shows to be using that much. This persists for a while and finally subsides until the next "trigger", where it begins to slow down for a minute or two again. The trigger is usually when I open a program such as iTunes or Mozilla. Below is my HijackThis logfile. Your help is much appreciated.

Hello , welcome to the forum.

Sorry about the delay in responding but we are being swamped with logs.

If you still need help, please run a new HijackThis scan and post the log in this topic.

It would also help if you can give some details about your problem.
