Guys do what I do, anytime someone sends you a link ask what it is first before you click it. Usually the hacked/virus thing doesn't respond to your question so then you should know not to click it.
I doubt this is just on msn. 3 schools in singapore just got hacked through a careless teacher whose acc in google was used to spread fake messages bout the ministry and luckily it was contained. Apart from that... that teacher was an ICT meaning he/she had access to the school website and editting it. You can't imagine what happened to the website......
