practical, consider encryption software. Encryption software scrambles a message or a file in a way that can be reversed only with a specific password. Also, make sure you keep your original software start-up disks handy and accessible for use in the event of a system crash.

3. Protect your valuable personal and financial information. Don't open unsolicited or unknown email messages. If you do get an email or pop-up message asking for personal information, don't reply or click on the link in the message.

Ask your bank, your regular online retailers, and your Internet Service Provider (ISP) if they offer stronger authentication tools for more secure transactions.
