What does it do?

2)    It encrypts all the files on your computer, and network drives attached to your computer and renders them permanently unreadable. Most variants    then display a “ransom” demand

Because of 2) the virus has the potential to completely destroy all the data on your computer and any folders it is attached to, even across a network.
