Computer Security Essentials

Five essentials for safe computing:

1. Apply security updates for your operating system and major applications. 
2. Keep antivirus software up-to-date.  You probably got a short-term license for antivirus software with your computer.  Do you have the most recent virus definitions?
3. Use a hardware or software firewall to close your computer's "gates, ports, doors and windows". If you have only one computer, a software firewall is OK if it's properly configured.  If you have a home or office network, use a hardware firewall. 
4. Use adware and spyware blocking software to keep your personal information safe and to keep your computer running smoothly.  Next to viruses, spyware is the most likely culprit if your computer is running slow. 
5. Avoid cutesy and/or unethical software like the plague, because that's what they are!.  Do you know what those free browser add-ins, file swapping programs and so-called optimizers really do?  Many come with adware and spyware that put your personal information at risk and bog down your computer. 

1. Use Firefox instead of Internet Explorer as your main browser.  Firefox has better security features and easy-to-use pop-up and ad blocking.  You'll love the extra speed, convenience and better appearance when you don't waste time and screen space with ads.  You can keep Internet Explorer on your system for connecting to Microsoft Windows Update. 
2. Use Mozilla Thunderbird instead of Outlook Express as your e-mail program.  The design and "features" of Outlook Express are inherently unsafe.  At the very least, turn off the message preview pane in Outlook Express -- it's like an open door to malicious mail, web sites, and spammers.
