Facebook viruses make you (and your business) vulnerable

Perhaps it's time to tell your employees to stay off Facebook while at work. And maybe it's time to tell your kids to also stop spending so much time posting status updates or clicking video links.

It's official, Facebook is the most popular social media network and because of that, it also causes businesses with Facebooking employees to be vulnerable to its viruses, or at least that's what 60% of companies believe. Perhaps that's because more than a third of the businesses were infected with malware, or software that installs malicious programs on computers. For those of you keeping count, that's approximately a 70% rise in 2009, according to Internet security company Sophos.
