The latest Facebook clickjacking scam takes the form of a blurb for a video supposedly describing how action film star Chuck Norris died. But as anyone capable of conducting a basic Internet search can easily find out, Norris isn't dead. The links are bogus.
Users who click on them are redirected not to a video about Chuck Norris, but to one of several pages asking the user to take an online survey, download a YouTube update, or apply for a free gift card, etc.
Any or all of these may pose a security risk to your computer and/or your Facebook account. Delete, don't click.
