Windows 7: Had Virus and Malware, can't open firefox or IE8

Thank you for all help, very much appreciated, problem solved.

Could you give a brief run down on how your problem was resolved which may help others?

Couldn't manually fix, tried everything members posted, also had a real good IT friend have it for 2 days. Being that my laptop is less than a year old, I didn't want him to really get into it. He couldn't get far, kept denying permission, also couldn't update malwarebytes. I remember it finding a backdoor cybot, thats about all it found, though MB cleaned it, but I was wrong. So, I used the recovery partition and restored computer. Wish I knew more, sorry.
