I looked for this control under the Security heading-but instead you need to double-click the System Preferences icon in the Dock, then double-click the Sharing icon in the Internet & Network section. Turning on OS X's firewall is a no-brainer, but finding it isn't. If your home network includes a router with a built-in firewall, it probably gives you the same kind of protection.

If enabled, the stealth mode makes your Mac invisible to incoming data inquiries, which is essentially the same thing that hardware firewalls do. The firewall has some advanced features, including activity logging and a stealth mode. The firewall is in the same System Preference window as the sharing services, and it lets you close all ports except those for services you want to allow. If you want to give other users access to some areas of your system, you should turn on the firewall that's built into OS X. If you don't use these features, you're protected by default.

The complacency about Mac security has some basis in fact: OS X comes with many of the ports that could allow snooping closed you have to change a System Preference to activate file sharing, personal Web hosting, or even printer sharing. (While Mac fanatics will insist that they're more sophisticated than the Wintel rabble, there are plenty of innocents in Apple-land as well.)

#Clamxav found a virus what now install
After all, Mac users are just as vulnerable as anyone to the social engineering used by many computer exploits to install themselves. But at Macworld Expo last month, I stopped by the booths of several security software vendors and began to wonder if they are pushing products people don't need, or if they know something I don't.
