Beware Conficker worm come April 1
In an event that hits the computer world only once every few years,
security experts are racing against time to mitigate the impact of a
bit of malware which is set to wreak havoc on a hard-coded date. As is
often the case, that date is April 1.
Malware creators love to target April Fool's Day with their wares, and
the latest worm, called Conficker C, could be one of the most damaging
attacks we've seen in years.
Conficker first bubbled up in late 2008 and began making headlines in
January as known infections topped 9 million computers. Now in its
third variant, Conficker C, the worm has grown incredibly complicated,
powerful, and virulent... though no one is quite sure exactly what it
will do when D-Day arrives.
Thanks in part to a quarter-million-dollar bounty on the head of the
writer of the worm, offered by Microsoft, security researchers are
aggressively digging into the worm's code as they attempt to engineer
a cure or find the writer before the deadline. What's known so far is
that on April 1, all infected computers will come under the control of
a master machine located somewhere across the web, at which point
anything's possible. Will the zombie machines become denial of service
attack pawns, steal personal information, wipe hard drives, or simply
manifest more traditional malware pop-ups and extortion-like come-ons
designed to sell you phony security software? No one knows.
Conficker is clever in the way it hides its tracks because it uses an
enormous number of URLs to communicate with HQ. The first version of
Conficker used just 250 addresses each day -- which security
researchers and ICANN simply bought and/or disabled -- but Conficker C
will up the ante to 50,000 addresses a day when it goes active, a
number which simply can't be tracked and disabled by hand.
At this point, you should be extra vigilant about protecting your PC:
Patch Windows completely through Windows Update and update your anti-
malware software as well. Make sure your antivirus software is
actually running too, as Conficker may have disabled it.
Microsoft also offers a free online safety scan, which should be able
to detect all Conficker versions.

Creo que el mejor antivirus es el usuario que está frente a la PC, puedes tener un buen antivirus, un buen antispyware, etc. pero si eres pendejo y te la pasas bajando programas del Ares 
pues casi seguro que agarras virus.
