It does this to try and scare the infected user into calling one of the listed numbers (1-844-208-3526) in order to receive support. In reality, though, they will only be greeted with people who are trying to sell them unneeded support contracts and services.

These “Call certified Microsoft technicians” are designed to scare you into thinking that your computer is infected so that you will call the number listed in the fake security alert.
