Oh yuck. Thanks for the info Missb. Be safe on facebook everyone!

Thanks for the heads up!

I have been hearing in the news also that the Koobface virus is reappearing.
If you don't know what that is you can find out more here the article is dated 03-09-2009 and at the end they say to be very careful about what you're downloading.

Like the variant that hit Facebook late last year , the newest Koobface tries to dupe users into clicking on a link that's included in a message from a friend. Clicking on the link displays a fake error message claiming that Adobe System Inc.'s Flash is out of date, and prompts the user to download an update.

The update is nothing of the sort, but is instead an executable file that installs the Koobface worm.

"Koobface.az," as Trend pegged the worm, rifles through a compromised PC, sniffs out browser cookies associated with 10 different social networking sites, uses the usernames and passwords within those cookies to log on to each service, searches for the infected user's friends, and then sends those people messages that include a link to the worm.
