It's good to have a toolbelt of IT resources at your disposal. One to bookmark for the future should you ever need it: https://www.nomoreransom.org
The No More Ransom Project has over 80 tools developed by big names in cybersecurity like Kaspersky, Avast, Bitdefender, and McCafee among others. Beyond tools to download that may help crack the encryption and return access to your files, they have best practice advice to defend yourself for the future, as well as the Crypto Sherrif which will attempt to identify which ransomware flavor is locking down a file you upload. Very cool stuff.
Thank you to all the Cybersecurity specialists involved with making the No more Ransom Project a thing.
