To help improve security on the site

Online security has been a major issue for a while, from the cases of spam emails to identity theft. Facebook might be a bit sloppy about privacy but security seems to have been their priority lately.
Sometime last year, Facebook introduced a two-factor authentication called Login Approvals, which, if turned on, requires users to enter a code whenever they log into the site from a new or unrecognised device. The code is sent via text message to the user’s mobile phone. They are also asked to identify pictures from their profile album or the ones they’ve have been tagged in.
Facebook has taken its fight against internet threats to the next level by creating a ‘Malware Checkpoint’ which directs users to sign up for either Microsoft Security Essentials or McAfee Scan and Repair once it detects that they are infected with a malware. For Mac users, they would be directed to Apple Security Updates site.
The good thing about the Malware checkpoint is that it opens users up to a variety of free anti-virus from top security firms.
“Now, with our new self-enrolment malware checkpoint, you will be able to proactively obtain your choice of a free anti-virus product to scan and clean your system,” Facebook explained.
