Twenty minutes. That's how quickly an unprotected computer can become infected on the internet, according to research institute Sans.org.
Ryan Purita, a consultant with Totally Connected Security Ltd., wanted to see this for himself. He hooked up a PC with default Windows settings to the internet: It had no anti-virus software, no firewall, and no operating system patches. In about one minute, says Purita, it was hacked, infected, and it had started propagating viruses to other computers. Purita recorded what happened in a video [RealVideo runs 2:00].
"Home users still lack the most fundamental education regarding security. When people enter in their PIN number at an ATM and people are around, they are aware and take steps to prevent disclosure of sensitive information. However, some of the same people will willingly fill-out their real name, address, phone number and even credit card information from an unsolicited email, or banner pop up," says Purita.
LOGGING OFF?

Tired and frustrated of their virus- and spyware-plagued PC, Rosslyn Berot-Burns and her husband Paul are seriously contemplating logging off permanently.
Their three kids protest, but each week brings more infections, and more time and money thrown at their problem machine. The past year has seen their system go through multiple crashes, a multitude of pop-ups, and their browser doing unexpected things. Even with an anti-virus program and a firewall, the computer's still getting infected, says Rosslyn.
Calling herself an average home user, Rosslyn says she doesn't understand how a lot of the programs work. What it comes down to, says Rosslyn,
is that the home users have to make it their responsibility to find out how to protect their machines.
"If you really want to have the computer, first of all find out what you need in order to protect yourself. Or don't use it. That's where I'm at right now."
