More information is needed to determine specifically what infection you are dealing with since there are many variants of crypto malware ransomware. What is the actual name of the ransom note?
This is likely a new variant of Globe Ransomware which uses the .zendrz extension and leaves a ransom note named "Read Me Please.hta"....see the comment here
You can submit samples of encrypted files and ransom notes to ID Ransomware
for assistance with identification and confirmation. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further assistance. Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections.
There is an ongoing discussion in this topic where you can post comments, ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.
Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.
