How to Avoid Awkward Situations on Facebook?

July 13, 2012 4:16am CST
Do anyone know how to avoid awkward situations on facebook? Like how to get rid of hackers and some other stuff like that. Recently I faced one issue in facebook that, there is a virus which automatically post some rubbish videos on our friend's wall without our knowledge. I clicked some stupid app so I got this problem. Do anyone of you got the same problem? If its so do you guys have any methods to get rid of that problem?
