Lol I love these threads. :P
Anyways, I have heard about this virus a few months ago, and yes, it is quite deadly. (To a PC lol)
When installed via .zip via email, it adds a "key" to the computer's registry that tells the PC to encrypt certain files of possible importance. (.pdf, etc.) After encrypting the files, a message pops up demanding a payment via "Bitcoin". Once the payment is made, the files will become decrypted and once again the PC will be back to normal. :P
I would type more, but most is above this post. xD
DO NOT open random, "legit" emails!
I couldn't agree more with you guys, and you're welcome for the warning. <3
