I noticed a common thread running through the forums and complaints: "I don't know where I got it, or how it got loaded onto my computer." I too am baffled. I hate browser bars and never allow extraneous stuff to load, but obviously this one functions by stealth.
Removal via about:config command typed in the browser bar (Url window) and then search for Mystart and incredibar, and via the Modify command (right click) delete each and every instance of the loathesome thing. It's working so far.
Be very careful with about:config, because misuse or careless use can void your Windows warranty. Don't delete anything you're unsure of, but if it has Mystart, or Incredibar in the right hand string you can delete without a worry.
I can't believe I successfully did this. I'm such a nebbish with computers. Hope I'm not celebrating prematurely.
