A couple days ago, some hackers made a virus called Ransomware, which enters your computer mainly as an attachment in an email, and it completely disables every file on your computer, until you pay the owner of the virus a certain amount of money in Bitcoins.

Ransomware is nothing new although usually they disguise themselves as some kind of helpful virus or hardware protector which would proceed to destroy your computer until you paid for the " premium" version of whatever you accidently got.
