Ransom ware comprises a class of malware which restricts access to the computer system that it infects, and demands a ransom paid to the creator of the malware in order for the restriction to be removed. Some forms of ransomware encrypt files on the system’s hard drive (cryptoviral extortion), while some may simply lock the system and display messages intended to coax the user into paying.

While initially popular in Russia, the use of ransomware scams has grown internationally; in June 2013, security software vendor McAfee released data showing that it had collected over 250,000 unique samples of ransomware in the first quarter of 2013—more than double the number if had obtained in the first quarter of 2012.

The Ransomware family ‘Reveton’ has been a thorn in the sides of many for over two years. It has employed a dynamic approach by tailoring the malware to specific countries and frequently changing infection methods.

Bascially this type of malware does the following :

Encypts your files on the server (If not all files on the server) meaning that the files need to be deleted and restored from backup. The PC that gets infected has to be wiped and reloaded.  The infection can spread to all the computers in a very quick period of time.

How do I get the malware?

Because each strain of malware is different, its almost impossible to detect every single strain, and thus some can infect computers and servers.

The main cause is from emails similar to the following :
