So I went onto Facebook, and I had gotten a message from a friend I knew in real life, it was a link so clicked on it. I'm pretty sure this is where I went wrong. It lead me to some video site and it told me to watch it I had to download flash player, and since my flash player had already tried to update itself and I cancelled it, I though it was just me. Then it downloaded setup, so I used that and nothing happened. so now I have this virus that redirects me to some other download site every time I try to enter a site. How to fix D:
