Computer virus exploits Windows vulnerability

From NBC12 News

RICHMOND, VA (NBC12) - There's a new disease in cyberspace affecting millions of computers, and yours might have it.

Experts say the new computer worm, called "Conficker" or "Downadup," is the worst infection since the Slammer virus in January of 2003.

The worm gets in through a recently discovered opening in Microsoft Windows vulnerability, and works by guessing network passwords.

Conficker can also be spread by USB keys, the portable little flash drive units.

When infected, machines tie into other infected machines to make networks called Botnets, which run off programs from their masters.

And computer owners may not even know their machine's been infected.

Microsoft made a patch to fix the hole in October but expert say about 30 percent of computers  are still vulnerable.
