UK’ers w/ ad infested sponsored LJ accounts may have been infected with pop up malware.

“LiveJournal recently introduced an ad-supported level. Over the last few days an advertiser used an ad to install the ErrorSafe malware that tried to trick people into believing they had a fault on the computer that needs them to purchase a fix. The ad used a server-side setting and targetted only those outside the US, to prevent LiveJournal’s own checks from noticing it. LiveJournal has apologized for the ad and slow response.”

LJ says “oops“.

Flash ads are bad, m’kay? Firefox and Adblock are your friends. Ditch IE.
