Close Notepad.

NOTE: It's important that both files, FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system

Run FRST64 and press the Fix button just once and wait.

If the tool needed a restart please make sure you let the system restart normally and let the tool complete its run after restart.

The tool will make a log on the Desktop (Fixlog.txt). Attach it to your reply.

Note: If the tool warns you about an outdated version please download and run the updated version.

If I can;t find two files, one before encryption and one after, what can i do?

It appears that all non-encrypted copies have been removed.

If you do not have a copy of an original and its encrypted copy, then the tool will not work.  Your only other recourse is to pay the ransom.
