DEP - A missed opportunity to protect millions of Windows users
Imagine coming across someone who had both an antivirus package and firewall software installed on their PC and yet both were switched off. You'd think that they were pretty dumb, way too brave or a little bit crazy (or they are antivirus researchers!). But the fact is that there are literally millions of Windows XP SP2 users who have a defense mechanism in place that would protect them against many of the vulnerabilities that threaten them, but that protection is, by default, partly disabled.
