According to All the latest news the attack takes control of your browser and attempts to download a trojan. Luckily, I clicked that link from firefox on my Mac which, for the time being, is largely unaffected by viruses. After clicking on the link, when i went into facebook, the site seemed to be disabled in many areas specifically, in the help and change password areas. At one point my password was changed and I couldn’t cancel my account or change the password.
I went on with another computer and reported the issue then requested a password change which was sent to my email. I also tried to take any personal info off of my account.
Next, I went through my files for firefox on the affected computer. I went into /Users/mims/Library/Application Support/Firefox. I backed up the contents then threw them away. I also trashed the firefox preferences in /Users/mims/Library/Preferences and the application itself. I downloaded a new version of the browser and installed it and the facebook corruption seems to be gone.
I haven’t heard anything from facebook yet and trying to contact them was a pain in the ass.
Good luck!
