Hello!
I thought Spybot would find these after I waited a few weeks after they affected me, but no! Opening Crome it goes to here AND it opens my homepage:

and Firefox wants me to d/l something called firefox.exe when I first open it! I have looked in my options for both to get rid of them, but no avail! I thought the Spybot search would detect them, but after a few weeks no! Help me get rid of them!! I had to edit my start-up of one or more programs and the Spybot did get rid of some, I deleted some bad things it created, but not all! HELP!!
