When dealing with e-mail
Tip #1: Don't mix business and leisure. Get an e-mail address for personal use. You have little privacy protection with company e-mail. Most businesses claim that it is their right and responsibility to monitor e-mail, because it represents the company, uses company equipment and travels over the company network. You could argue the point, but getting a private e-mail address is much easier. Then use your business address for company business only.
Tip #2: Use encryption software. Unless you encrypt your messages--essentially scrambling the data--your e-mail is no more private than a postcard. An easy-to-use encryption program you can download for free is PGP.
Tip #3: Don't reply to spam. Sure, junk e-mail is a nuisance, but it's easier to get rid of than the paper kind--just hit the Delete key. If you reply to the message, asking to be removed from the list, it just confirms that your address is valid. You will soon be spammed and spammed again.
Tip #4: Remove old e-mail from your computer. When you delete a message, it's still on your system. To permanently remove it, open the Deleted Mail folder, highlight the message and delete it again.
Tip #5: Be aware that the message may still reside somewhere on your computer. A trained technician may be able to recover it. Messages may also remain on the mail server and be archived on file back-ups.
When dealing with Web Browsing
Tip #1: Turn on the cookie alert. A cookie is a small file sent to your web browser by a web server to record your activities on a particular website. To block the cookie, set your browser to warn you before a cookie is written to your hard drive, then decide whether to accept or reject it. Here's how:
If you use Netscape Navigator, go to the Edit menu, choose Preferences, then click on Advanced. Now check this box: "Warn me before accepting a cookie."
If you use Internet Explorer 5.0, go to the Tools menu, then select Internet Options. Next, click on the Security tab, then click on the Custom Level button. Scroll down the list. Under the Cookie category, check the Prompt option.
Tip #3: Websites that collect personal data may allow you to decide whether the data can be shared with third parties, such as marketing companies, and whether you want to receive e-mail offers from them. Typically you check a box, either agreeing to this or refusing. You have no obligation to share your personal information with anyone, so opt-out if the offer holds no interest.
For more on opting-out, and an easy way to notify sites that you want to opt-out, visit the Center for Democracy and Technology.
Tip #4: Make sure your computer is secure. If you access the Internet with a dial-up account and modem, the chances of data theft are minimal. But if you have high-speed Internet access, such as DSL or a cable modem, watch out. With these "always on" connections, you become a more likely target for hackers.

If you don't get a clean report, install a firewall. One program we recommend is ZoneAlarm. You can download it for free from ZoneLabs.
Tip #5: Clean up your history files, location bar list and cache. As you surf the Web, your browser both records the addresses of where you have been and stores downloaded files in a cache. If you want to keep this information from prying eyes, clear the temporary Internet files, delete the history files and the drop-down list under the address or location bar. While this may seem an extreme step, if you share a computer, or use a public computer, consider doing this. Here's how:
If you use Netscape Navigator, go to the Edit menu, choose Preferences, then click on Navigator. Now click on the Clear History and Clear Location Bar buttons.
Next, To clear the cache, double-click on Advanced. Now click on Cache. Finally, click on the Clear Memory Cache and Clear Disk Cache buttons.
If you use Explorer 5.0, under the Tools menu, select Internet Options. Now click on the General tab. Next, click on the Delete Files and Clear History buttons.
