What is a .Meds file? A file with the .meds extension is a file that has been affected by Meds ransomware that also known as crypto virus. All files with this extension become locked. Even if you remove ‘.meds’ or change this extension, file access will not be restored. The reason for this is that the files are not just blocked by changing their extension, but they are encrypted by a ransomware virus.
Meds virus is a new ransomware. It uses complex digital algorithm in order to encrypt (lock) users’ data. The documents, photos and music will be decrypted only if a victim pay for the private key that will unlock these files. The Meds ransomware virus encrypts almost of files, including common as:

After penetrating a computer, the virus sequentially encrypts all files, even those located on connected external and network drives. When the file is encrypted, its extension changes to ‘.Meds’. This is done so that the victim immediately noticed the result of the ransomware virus. So that the victim can determine the reason why the extension was changed, why suddenly the files stopped opening in regular programs, the Meds virus, in each folder with at least one encrypted file, creates a document with the name ‘_readme.txt’. In this document, the authors of the virus report that the only way to return the files – is to pay a ransom. Text presented in the ransom note:
