I and a few others I've heard from have been targeted in the past few days from a hacker on Twitter. You will see that you got a direct message from one of the people that you follow, or follow you, and it will saying something along the lines of:
You seen what this person is saying about you? terrible things..
As part of the message there will be a shortened URL... do not click this!
Now if you're anything like me, you probably thought, "who would say horrible things about me?" because, "I thought everyone loved me?"
Luckily this is just a virus and you can stop it. Everyone still loves you too.
Just warn your fellow Twitter-users about the virus.
