The README.txt files are dropped in many folders on the affected system. Most likely in every folder that has an encrypted file in it.

Type and source of infection

Ransom.Troldesh is ransomware. Ransomware is a type of malware that prevents users from accessing their system or personal files and demands ransom payment in order to regain access.
Ransom.Troldesh is spread by malspam, typically in the form of attached .zip files. This ransomware sometimes uses a CMS on a compromised site to host downloads.

Aftermath

Ransom.Troldesh uses a strong encryption, so sometimes there is no way to regain your encrypted files for free, but there are free decryption tools available for some of the Troldesh variants. Check NoMoreRansom.org for your options.
