In this case I suggest that you pop over to "Am I infected?" and post in; follow directions there and someone will help you check out your system. It may (or may not) take a couple of days, but someone will get back to you. In the meantime:
> Disconnect from the internet, especially if you do banking online, have personal identifying data stored on your computer, CC numbers, D. License number, etc. Do not use the internet again until one of BC experts tell you your computer is clean. Viruses can hide, send information back to a hacker and you will never know it.
> Download and run Malwarebytes and allow it to remove anything it finds.
> Download and run Malwarebytes Anti-Rootkit and allow it to remove anything it finds.
> Download and run Hitman Pro and allow it to remove anything it finds. Use the trial free version and delete it after it is finished.
> Use your existing antivirus to run a deep scan of your computer.
This will not guarantee your computer is clean, but it will get you started. Nothing should ever shut down your firewall without your permission.
[EDIT: Clarification]: Of course, you will have to be connected to the internet to download, install and update the indexes of the scanners, with the exception of your antivirus program which should be updating itself regularly. However, I suggest you not contact any sensitive websites (eg: banking) while connected.
