Security researchers say a worm that has infected millions of computers worldwide has been reprogrammed to strengthen its defenses while also trying to attack more machines.
Conficker, which takes advantage of a vulnerability in Microsoft's software, has infected at least 3 million PCs and possibly as many as 12 million, making it into a huge botnet and one of the most severe computer security problems in recent years.
Botnets can be used to send spam
and attack other Web sites, but they need to be able to receive new
instructions. Conficker can do this two ways: it can either try to
visit a Web site and pick up instructions or it can receive a file over its custom-built encrypted P-to-P (Peer-to-Peer) network.
Over
the last day or so, researchers with Websense and Trend Micro said some
PCs infect

Intel
used the first day of the Spring IDF in Beijing to show off its Moorestown
integrated processor, which is expected to replace the current Atom CPU and
chipset later this year or early 2010. The company also introduced two new
Z-series Atom processors.
It was the first time that a Moorestown chip was shown live to the
public. What makes this processor special is the fact that it
integrates graphics and all other chipset components on-die, which will
make it substantially smaller and apparently less power hungry than
today’s Atom generation.
Moorestown is promised to run at ten times less idle power than the current Atom platform.
Intel declined to reveal how much power the chip will actually consume
and, at least for us, it is difficult to estimate that number. Today’s
Atom relies on a 45 nm processor as well as an older chipset design,
based on an updated i915 version, which is called System Controller Hub
(SCH) as part of the Atom platform. The SCH is man
