-McAfee Logo-Facebook takes security seriously and tonight the company is increasing it even more by providing free anti-virus software to all Facebook users. It appears to be a joint promotion with McAffee, who requires you to become a fan in order to download the 6-month subscription. It’s important to note that this is only for PC users (yes, Mac users are fortunate enough to have no need for anti-virus software). This is not the first time McAfee has done a partnership with a large internet company.

At AOL, users were able to download free versions of the McAfee software. The purpose is to get users to convert to paying customers after their 6-month subscription has ended. It’s a standard promotional model and it’s one that worked extremely well for AOL as well. In contrast to AOL though, who charged a monthly fee at the time for using the service, Facebook is completely free.

If you want to get a free copy of the software (because you have an insecure PC that’s running Windows), you can head over to the McAfee fan page and get a copy now.
