Is accessing the web from public computers at libraries, Internet cafes, airports, and copy shops safe? That depends on how you use them.

If you follow these steps you can help keep your personal and financial information private.

Don’t save your logon information.
If you are browsing secure sites that require a login, then always log out. You can do this by clicking the “log out” link on the site. It's not enough to simply close the browser window or type in another address.

Many programs (especially instant messenger) include automatic login features that will save your user name and password. Disable this option so no one can log in using your stored information.

Don’t leave the computer unattended with sensitive information on the screen.
If you have to step away from the public computer, log out of all programs and close all windows that might display sensitive information.

Erase your tracks.
Web browsers such as Internet Explorer keep a record of your passwords and every page you visit, even after you’ve closed them and logged out.

To disable the feature that stores passwords:
Before browsing the Web, turn off the Internet Explorer feature that “remembers” your passwords.

1. In Internet Explorer, click Tools, and then click Internet Options.

2. Click the Content tab, and then click AutoComplete.

3. Click to clear both check boxes having to do with passwords.

Delete your temporary Internet files and your history.
When you finish your use of a public computer, you should delete all the temporary files (cache) and your Internet history.

1. In Internet Explorer, click Tools, and then click Internet Options.

2. On the General tab, under Temporary Internet files, click Delete Files, and then click Delete Cookies.

3. Under History, click Clear History.

Watch for over-the-shoulder snoops.
When youuse a public computer, be on the lookout for thieves who look over your shoulder or watch as you enter sensitive passwords to collect your information.

Don't enter sensitive information into a public computer.
The ultimate measure of security you can take is to not enter sensitive information at all on a public computer. The steps listed here provide some protection against casual hackers who use a public computer after you have.

However, you should bear in mind that an industrious hacker might have installed sophisticated software on the public computer that records every keystroke and then e-mails that information back to him. If that is the case, then it doesn't matter if you haven't saved your information or if you've erased your tracks. They still have access to this information.

If you really want to be safe, avoid typing your credit card number or any other financial or otherwise sensitive information into any public computer. If that is not an option, these tips should keep you safe in most situations.
