Facebook has announced a partnership with McAfee to offer its members a complimentary six-month subscription to security software.
"This is a first-of-its-kind security offering that represents a major milestone in the fight to secure the internet and reduce global cybercrime," McAfee said in a statement.
By submitting your personal information, you agree that TechTarget and its partners may contact you regarding relevant content, products and special offers.
After the six-month period expires, Facebook members will be eligible for discounted subscriptions to McAfee's security software.
The partnership will also enable Facebook members to scan and clean computers if infected, and learn security best practices.
Facebook has said the partnership will benefit its 350m-plus users, but McAfee's software will not work for members running Mac OS X or Linux, according to US reports.
About 5% of internet users are running Mac OS X and 1% are running Linux according to web marketing firm NetApplications, which means 21m Facebook members will not benefit from the initiative.
Social networks like Facebook, Twitter, YouTube and Digg were the most popular channels for malware distribution in 2009, according to the annual report from PandaLabs, the anti-malware laboratory of Panda Security.
