Facebook viruses have been around for a while, but lately I’ve seen them cropping up even more frequently. You get a Facebook virus when you click on a link that installs malicious code or if you allow an untrusted application access to your account. The links most people click on claim to tell you who has been looking at your Facebook profile (catch those stalkers and ex-boyfriends in the act!) or allow you to watch a video of something “you won’t believe!” or even a video of you (What were you doing here? That’s crazy!). Facebook viruses are becoming harder to discern.
