A new scam uses direct messages on Twitter to tease potential victims with a link to an embarrassing Facebook video. Try to view the clip and you'll download a virus.
You receive a Twitter direct message that seems to be alerting you to a video of yourself posted on Facebook. Senders try to grab your attention by implying that the video is embarrassing.
The message contains a link that appears to go to a Facebook.com address. But users who click on it are greeted with what appears to be a video player and a warning message that "An update to Youtube player is needed." The message says it will install an update to Flash Player 10.1 but the file that downloads isn't a new version of Flash.
What to do if you think you've encountered a scammer.
