The malicious encryption virus, Cryptolocker, is being reported more frequently recently, and it could pose a threat to your business. This encryption device, should it be opened, downloaded or accessed, will put a lock on crucial files on your system and may demand a payment for it to be released.
These types of Cryptolocker viruses will often come equipped with a timer function that, once it has reached the end of its countdown, could mean your files remain locked forever.
When businesses are attacked by this sort of virus, it can have a devastating effect in a rapid amount of time, wiping entire databases and records. Cryptolocker can cost businesses a huge amount of time and money, so being aware of the threat and knowing how to avoid it is vital should you come across this attack.

What types of file can it lock?

What can I do to help prevent an attack?
