Hello and welcome to Bleepingcomputer.
I read your description and realize you are in quite a jam.
One thing you do not want to do is run any registery programs as those can add insult to injury and often add to the problem rather than fix it.
I want to suggest a program that may run on your computer, its worth a try, I want you to download MalwareBytes anti-malware, install it, update it, then do a full system scan.
Here is the download link please click the FREE version button at this link. Mawarebytes Anti malware http://www.malwarebytes.org/
I realize your also suffering issues with possible operating system corruption as well, we can work through a possible repair of your operating system once we know your computer is clean of any malware.
Kind regards and good luck.
If this program fails to function, please post back, there are ways to get scanners to run one way or another.
