My little brother had downloaded a virus from facebook recently (Someone pmed him it or he downloaded it from an app), which blocked access to facebook (A little fake message saying that there is tech. difficulties) . After the virus was gone(Well, I think I got rid of it. There may be a small trace somewhere, I'm not sure.), I got a message about teamviewer using port 80 when I went to facebook. So I disabled port this port 80 usage in teamviewer, and now all I have is a blank screen. Any help? Also, Malwarebytes blocked a few IP's as I was removing the virus, maybe one of those was facebook. If so, how do I unblock? EDIT: I originally posted this on yahoo answers and all I got was 'hurr-durr internet use port 80, why did you turn it off" so I came here in hopes for someone who could actually help me.
