As a general practice in the security community, any decryption tools that have been developed are usually shared by the developer for free. Once identified, you may know what common locations any remaining infection may occupy, the scope of the attack, and whether or not a decryption tool exists that would allow you to recover your files.
For this reason, the best start when cleaning infected devices is to identify the ransomware variant that attacked your devices: However, sometimes secondary malware is installed to attack the system again, or even allow further breaches. Removing ransomware is usually not required because most ransomware often delete themselves after executing (running). Our virus lab is unable to decrypt any encrypted files affected by ransomware, nor do these encrypted files contain any useful data to add to our virus definitions. Immediately disconnect ransomware-infected devices physically from the network to prevent other devices in your network from getting infected!
The best protection against this type of malware is to keep separate backups in a location not on your main network. Even after paying the ransom, there is no guarantee that you can recover your files. Ransomware refers to malicious software that encrypts important files on a device and then threatens to publish the victim's data or perpetually block access to it unless a ransom is paid.
