I’ve spent some time around a computer store that does a booming business repairing security disasters that never had to happen. Fortunately the old saying about an ounce of prevention being worth a pound of cure holds true in this area.
It doesn’t take much time, money or expertise to secure your computer, especially compared to the cost of repairs or lost work! You just have to know what to do and then do it. That’s where this booklet can help, whether you’re using a Windows PC, a Mac, or even Linux. Taking a few simple steps now can prevent huge headaches later!
If you’re stumped by any of the technical jargon in this booklet, please see the glossary on page 18.

Malicious software installed on a computer that steals information from the computer without the owner’s knowledge. Often masquerades as a game, video player, or other desirable program.

These tips will help keep your computer secure, especially against the threats that have proliferated as the Internet has become popular. Although this booklet has given you many steps you can take yourself, probably the best advice I can give you is don’t hesitate to get professional help. I have an IT consultant, and so should you.
If your computer is for personal use, a friend or neighbor might do, but if you’re using your computer for work, hired help is a must. I live in a small town, and even here there are IT consultants who make house calls. Ask for a referral from your local computer store, or look in the Yellow Pages. Have someone come to your home or office and give your system a security checkup. Depending on the amount of work needed, the cost could be less than a hundred dollars—dirt cheap compared to the cost of a compromised system. Plus, your consultant should be able to help you resolve any nagging issues with your computer, and make suggestions for how to improve your productivity while working with common applications like Microsoft Office.
