Facebook is concerned with the security of its users and wants to make their experience on Facebook more secure. To achieve this Facebook is providing license for 6 months for 5 major antivirus applications. A user can select any one antivirus from McAfee Antivirus for 6 months, Norton Antivirus for 6 months, Trend Micro Internet Security for 6 months, Microsoft Security Essential (It’s free), and Sophos Antivirus for Mac.
Just go to Facebook’s Antivirus Marketplace Page and choose your antivirus and get it free for 6 months. After the 6 month’s period create a new Facebook ID 🙂
