Here is my hijackthis log. Any help is greatly appreciated!!

My computer shut down upon replying to an email.  My internet homepage will not stay the same.  On 8/6/04 I noticed lots of files had downloaded and my virtual memory was low.  I installed spybot and ad-aware.  It found 1944 files.  Sorry I deleted those.  It worked mcuh better for about 12 to 15 hours and is currently changing my home page again.  I am unable to surf without getting hijacked.  I unchecked some of the items on start-up. When I run spybot and ad-aware it finds 6 to 8 files now.  It has locked-up some today while trying to search different web sites.      I'm wondering if my computer needs formatting? I'm hoping you can help!!! THANKS!
