Just got word from TechSpot.com that they have posted a new guide to Windows security! Here's a snip

This guide will cover some of such tips and tricks for different applications which should make your system more secure as well as less prone to viruses. Although the guide is mostly aimed at Windows 2000/XP users, people using older version of Windows should also take note as much of the content here applies to those earlier versions in addition to the Internet Explorer and Outlook Express tips.
