I have just been sent this message: Advice: While on FB, look at your URL address (very top box on your screen.) If you see "http:" instead of "https:" then you DO NOT have a secure session & can be HACKED. Go to Account - Account Settings - Account Security - click Change. Check box (secure browsing), click Save. [It is auto set on non-secure!] Do your friends a huge favor, copy and paste this onto your newsfeed. It might be of use to you.
