The apocalypse has been cancelled. No rain date has been set.

Everyone and his brother is chattering away about the Mayan apocalypse, which supposedly happens tomorrow. If you’re just now learning the world might end, you might be tempted to Google around for more info. Just don't open any sketchy powerpoint presentations on the matter, Naked Security warns.

That's because there's one circulating with the SEO friendly title of "Will the world end in 2012?" and it's brimming with malware.

You open the document, enable macros and boom, nasties on your hard drive. So tomorrow the world will turn on, but your computer will be compromised.

Naked Security explains where this little Christmas present originated:

The presentation about the world ending was created by a preacher in the United States who appears to have nothing to do with this booby-trapped version. Don't go looking for this presentation though!

His legitimate WordPress blog has been compromised and is currently performing search engine manipulation duties for Viagra pushers, "off-shore" casinos, forex fraud and payday loans.

Spammers--or the planet Nibiru???

Though NASA has already gone to great lengths to assure adults everywhere that rumors of the world's supposed impending demise are in fact false, the government has now turned its focus to precocious teens who have traded in anxiety about what to wear for class picture day for soul-crushing fear of the apocalypse.

On USA.gov, which is apparently "the U.S. government's official web portal," some enterprising government intern wrote a short blog post meant to assuage the worries of America's angst-ridden tweens. No comets or stray planets are coming to collide with our own, we promise!

NASA has received thousands of letters concerned about the end of the world. David Morrison, a planetary astronomer and senior scientist for NASA who answers questions from the public about astrobiology, says, “At least a once a week I get a message from a young person ― as young as 11 ― who says they are ill and/or contemplating suicide because of the coming doomsday.”

Young people, always remember that if you're feeling upset about doomsday rumors, Neil Degrasse Tyson has your back.

NOPE, ALL BULLSHIT.

We're less than a month away from December 21, which some people genuinely still seem to believe will be the end of the world, as predicted by the Mayans. And so, NASA is spending the holiday season--a time when everyone ought to be sneaking nips of eggnog and picking out their ugliest season sweaters--making one last attempt to diffuse everyone's paranoia.

What, Neil deGrasse Tyson, super scientist, wasn't a respectable enough authority?

CNET reports that yesterday, the agency held a Google+ Hangout specifically to discuss rumor's of the earth's imminent demise. On the call were experts in asteroids and also an archaeoastronomer. All of them agreed: The world is not ending. There'll be no wandering planets or rogue asteroids or boiling seas or shifting tectonic plates before the end of the month, so go right ahead and wrap those presents.

And actually, it sounds like all this is really starting to upset the agency's resident astrobiologist:

"In particular I'm concerned about the young people who write to me and say that they are terribly afraid," Morrison said in response to a question during a Google+ Hangout NASA held yesterday specifically to address 2012 apocalyptic hoaxes. "They can't sleep, they can't eat, some of them say they are contemplating suicide."

Again: The world is not ending. Repeat: The world is not ending. Go back to your lives, citizens.
