The net-net of the article is that both security software such as  rootkit detection products and ESPECIALLY antivirus software really don’t protect users against rootkit installations.

ANTIVIRUS IS NOT ENOUGH
No antivirus program tested was able to detect all the rootkit vectors they were tested against, meaning that the world for the most part is vulnerable to some sort of rootkit, being that most people only have antivirus software installed on their machines as opposed to specialized anti-rootkit tools.

VISTA UAC SAVES THE DAY
Windows Vista User Account Control however was able to detect & block every rootkit installation attempt.  This provides users with at least a fighting chance to defend themselves from rootkit installations.
