Hackers Increasingly Turning Computers Into 'Zombies'
About a half-million computers worldwide are estimated to be infected, and disconcertingly that number is accelerating, not slowing, as those who run these underground zombie networks seem to be consolidating their forces for greater harm. Computers are typically infected through browser exploits, such as the one recently uncovered in Google's Chrome. But the number one way many computers are infiltrated remains human gullibility -- hackers still do their best work when they trick people to download software they think is one thing but is actually something bogus.
Your best defense is to simply be careful where you surf and what you download -- and, of course, to install a virus scanner. [Source: BBC News]
