The creator of STOP ransomware released another file-encrypting virus known as Coot. If you failed to access text documents, images, videos, databases, and other personal and valuable files on the computer, it simply means that Coot is bugging your system. This virus targets those files and renames it by affixing .coot extension.

When the encryption process is completed, it drops a _readme.txt file on a victim’s windows desktop. It contains details about what happened to your files and how to restore it. Coot ransomware states that your files are encrypted with strongest encryption and unique key. It stresses out that the only way to decode all infected files is by paying for a decrypt tool. In other words, the Coot virus placed a ransom note.

Coot ransomware demand victim to pay $980 in exchange for a unique key and decrypt software. It also gives a 50% discount if you contact them within 72 hours. Malware author advised victim to send an email to salesrestoresoftware @
