Thanks to listener David for sending this over.
I was listening this morning when you were discussing the ransom-ware virus. Please urge people not to pay the proposed fee. I fixed it by manually restarting my computer, then when the option for the screen with start up options appeared I pressed the key specified repeatedly. In my case F8. I believe that it is usually F8. That will open the advanced boot options menu.
There should be a "Start in safe mode with command prompt." option. Select this when the computer restarts a the command prompt will show up when the windows has restarted. I typed rstrui.exe. This is the command for the system restore software. I just selected the last date that I knew my computer was working. It restored back to that point and has worked fine since. Hopefully this might help some people. I know not everyone will feel comfortable with this, however it is better than paying the $350.00 it was asking me to pay.
