These days, a firewall, anti-virus software and anti-spyware programs are essential, but they might not be enough to protect you.
This is a change from an earlier recommendation that you turn it off to save energy.
Security software and your computer's operating system are regularly updated to counter new viruses, worms, spyware and hackers probing for weaknesses. If your computer is off at night, you'll have to update during the day, when you're working. Or worse, the new threat hits your system before you have a chance to download and install the updates. Turn off the printer, monitor and other extras, and find other ways to save energy.
You can prevent others from taking control of your computer by giving up some privileges. Too many people use Windows Administrator accounts when they run their computers. Users with administrator accounts can install software and change system settings. So, if you use the Internet with a limited account, and you click on the wrong thing, malicious programs cannot install themselves on your computer.
To create a limited account, click Start, Settings, Control Panel, then User Accounts. Select Limited and then click Create Account.

These days, most adults are fairly cautious about disclosing e-mail addresses. Teens may be more naive, particularly when an e-mail message preys on their insecurities.
