Facebook has joined forces with McAfee to provide discounted security services to all of its 350 million members. But there's also a security element to Facebook's decision as well.

Facebook has joined forces with McAfee to provide discounted security services to all of its 350 million members.

Facebook users will be eligible for a free, six-month trial of McAfee Internet Security Suite software and a discounted price thereafter.

If Facebook uncovers any sort of threat, the social networking site said it would take steps to secure a user's computer, a process that includes a sweep of the affected computer by McAfee technology.

"Now, if your computer is infected, you will be asked to run a scan and clean it before accessing Facebook," Facebook wrote in a blog post.

At launch, the McAfee software will be available to Facebook users in the U.S., U.K., Australia, Italy, Germany, the Netherlands, Spain, France, Canada, Mexico, and Brazil. Other countries will be added throughout the first quarter.

To access the software, click the "Protect Your PC" tab on the McAfee Facebook Page.

"Facebook is very serious about security and has made significant efforts to protect its users and service by investing in dedicated teams and sophisticated systems, and this partnership with McAfee furthers that mission," Todd Gebhart, executive vice president and general manager of McAfee Consumer, Mobile and Small Business, said in a statement.

"By partnering with a market leader like McAfee, we are taking an unprecedented step towards making the entire Internet more secure and reducing the possibility of threats being brought onto our service by unsuspecting users," said Elliot Schrage, vice president of global communications, marketing and public policy at Facebook. "Keeping the Internet secure requires that users, security vendors and Internet companies all work together. We think we've developed an excellent model for this collaboration, and to ensure the greatest possible value to our users, Facebook will not accept any revenue from subscriptions. We hope this is something that other services will emulate."

In addition, Facebook and McAfee will work together to develop content for the Facebook Security Page, and McAfee will frequently update its own page.
