I think my computer recently got hacked help!?

You may be contacted by the hackers to pay a ransom for your files but I wouldn't count on it. Definitely stop booting from the hard drive! I would get a copy of one of the Linux distros on live cd (Knoppix would work) and try to recover files that way. Foremost and magicrescue are the tools on the disc that will help you recover deleted files.
