There is a new ransomware being seen around the world.. It has sloppy coding and is slow, but it can still encrypt/ransom files. It may be just targeting businesses.

Below is a MDB signature for this malware. Copy the signature to a Notepad file and save it in the ClamWin db program data folder. When you save the file, do not save it with a .txt or .text on the end. Just save it as Sigfile.mdb (select type All Files to prevent the .txt or .text at the end of the filename), otherwise ClamWin will not recognize it as a signature. The MDB signatures are for important parts of a malware and will last until the next version of the malware comes out--usually in a couple of weeks, but some malware authors reuse the same part again, so this signature might last for a month or so.
