HELP NEEDED IMMEDIATELY!

My files have been locked by MotoxLocker ransomware – I have just saw the ransom note. Guys, I must recover my files, the sooner, the better. Is that even possible? Please tell me that it is… I am desperate right now, I can’t forgive myself for being so inattentive! I have opened a phony email attachment and it infected all my system. I haven’t removed MotoxLocker virus yet, because I wanted to ask for instructions on how to do it. Can you provide them…?
