PCWorld: Although it's six years old, many people still run Windows XP service pack 2 (SP2). Tomorrow, Microsoft releases the last security patch for the operating system, meaning that if you continue to run SP2 after tomorrow, you face a greater risk. The easiest solution is to upgrade to SP3, but if you're committed to sticking with SP2, here's what you can do to help protect your system:
- Stop using Internet Explorer.
- Update your third-party software, especially browser plug-ins.
- Install anti-virus software.
- Use a firewall.
- Don't visit disreputable sites or open suspicious e-mail or attachments.
