I don't know if this will help, but I got this virus about a year ago. I had set up a second account on my PC that I accessed and reset the computer to a previous restore point, prior to the virus. It went away and has not been back, yet......

In my case, it blocked me from using the computer. It would run for about a minute but then a ransom message popped up. It did not go after any files AFAICT.

Geek Squad basically told me to wipe out the hard drive & start over again. I was not willing to do that.
