It goes without saying that you should double- and triple-check your Facebook privacy settings. Make sure you haven't missed any. One crack in your security can lead to a hacker unraveling everything.

Security software can help, too, if you accidentally click on a scam link. You'll find plenty of free options for that in my security center. These can catch a virus before it becomes a major problem on your computer.

It won't catch everything, though. You have to be vigilant and know exactly what scams to watch out for. There are sites like Snopes and Facecrooks that will show you some. Every Facebook user should read my roundup of the most popular Facebook scams, too.

There are even some third-party apps that scan your profile for scams. Social Media Scanner made by anti-virus company ESET, is a powerful one to try.
