Yep, that's what I've been telling people:
Security - Back To Basics
"Now, I am wondering whether "security" peddlers realise that slapping a piece of software onto a vulnerable operating system in an attempt to protect the system is analogous to trying to put out a fire by pouring scotch onto it. Perhaps they do, but it's just that they also know that arson is a cash cow."
"These "security" peddlers are selling the idea that any Tom, Dick or Harry could simply swallow their "magical pill" (software) and enjoy instantaneous total security. Give me a break!"
Now, a software engineer who's been examining the goods for two years explains in length why he thinks security software is a security risk.
