Browsers also track passwords. Before going on the web, if you're using Internet Explorer, click Tools > Internet Options . On the Content tab, click AutoComplete. Clear the four boxes.
When you finish surfing, again click Tools > Internet Options . Go to the Content tab and click AutoComplete . Click Clear Forms and Clear Passwords.
If you're using Netscape, click Edit and Preferences . Click the arrow next to Privacy and Security . Click Passwords . Clear the box next to Remember Passwords . When you finish browsing, click Passwords again, under Privacy and Security. Click Manage Stored Passwords. Select the Passwords Saved tab and click Remove All.
Netscape has a feature similar to AutoComplete. It saves data entered into forms. To disable that, under Privacy and Security, click Forms. Uncheck "Save form data from Web pages when completing forms." When you finish browsing, return to the Forms page. Click Manage Stored Form Data. Click Remove All Saved Data.
Cleaning out the browser will ensure that no one can track your surfing or grab your passwords with saved data. But a keystroke-logging program will still catch your passwords.
