All computer software contains errors, especially computer software that is very large such as an operating system like Windows and UNIX. While no system is 100% secure, Windows users especially are most vulnerable to flaws in Windows software and computer viruses, so they need to update it at very regular times.

The best way to protect a Windows computer is

1. make sure your Windows software is up-to-date (Windows Update)
2. use anti-virus software and keep it up-to-date (daily update, automatic)
3. use a firewall to prevent unauthorized access from the network [ optional but preferable ]
4. use anti-spyware software and keep it up-to-date [ optional but preferable ]

While a firewall and anti-spyware are not really required, a firewall is a very good addition to protecting your computer. Windows XP includes standard a firewall, though you will have to activate it first.

To activate the firewall in Windows XP
1. Open Start and choose the Control Panel
2. Choose Network and Internet Connection
3. Click on Network Connections
4. Select Local Area Connection and click Change settings of this connection
5. Click on the Advanced tab...
6.... and click Protect my computer and network by limiting...
7. Click OK

Computers that are not connected to the network AT ALL are safe from network intrusions, but not necessarily from computer viruses or other malware !

UNIX administrators (including Linux) should subscribe to mailinglists to keep themselves up-to-date with the latest security issues, and should also regularly update their system.

MacOS X users can use the Software Update from the System Preferences under the Blue Apple menu to update their system at regular times.

AVOID ZoneAlarm until further notice. Versions 6.0.631.003 and above show several issues, older versions seem stable enough to continue using them.
