I think I have some spyware or a virus on my puter.  Every time I open internet explorer my home page defaults to some generic search page, like the kind you get when you misspell a website...  I change the site back to my home page and next time I open ie, it goes back to the generic page.  Ran a virus scan and came up clean so I think it is spyware.  Is there a way to check this out?
Puter seems to be running a little slow, could just be my imagination.  
Thanks,
Bob
