The problem may have come from rapidfire.com . I was surfing alexa and went to the site and eventually it forced me to reboot the pc. I also saw it in the objects in IE when I was deleting them.
Here is info on the site:

Thanks for all your resonses, I will post more details later, as I have moved to another computer for now.
