This is the result of the STOP Ransomware attack. I have been tracking the malicious work of this program since December 2017. 
Now on the forum a lot of victims from different variants of this Ransomware. In some cases, the files can be decrypted. 

I do not see here a ransom note _readme.txt with your ID here that I can say something. You need to attach a ransom note to the message, or farther act by himself.

@Demonslay335  (the developer of the STOPDecrypter) collects information from the victims, writes data and tries to update the STOP Decrypter. After that, victims can try to decrypt the files. A positive result and a lucky chance are not always possible.

I recommend to you start decrypt with a small group of files, but first you need to make copies of these files.

If STOPDecrypter won't be able to recover your files yet, it can still be used to get information that may be able to help the creator of STOPDecrypter figure out your decryption key. Here's a link to instructions on how to get this information with STOPDecrypter:

While most ransomwares will automatically delete themselves after they finish encrypting files, some are now leaving behind components on computers they infect that will encrypt any new files saved and will encrypt any files you manage to decrypt. It's best to check and make sure that no such components have been left behind, so I recommend following the instructions at the link below to get us logs from FRST so that one of our experts can make sure there is nothing malicious still on your computer (please attach the log files FRST saves to a reply to this topic on the forums):

Note: If anything that appears suspicious is found in your logs, then your post will be moved into a new topic to facilitate better communication between you and whoever is assisting you. We'll also try to make sure that you are following the new topic so that you receive e-mail notifications when someone replies to it.
