I agree, Wolfgang's little article here is refreshingly like news instead of the author's opinion. Well done!
I have long thought of the typical good antivirus programs we use as filters that stop the most common infections; I don't think they should be seen as more than that. Real security requires real work, not just an addon program, but an in-house effort to keep the smart guys at bay.
Of course, one of the best anti-malware things you can do is only allow programs to run on your computer that YOU started. Unfortunately, many people can't be bothered with a couple of extra mouse clicks, and turn off things like Window's UAC. Doing that is like saying "Sure, come into my house and do whatever you like, it's all good by me! Take my TV screen, my fridge, anything you want!"
The worst program offenders though aren't anti-malware programs that let things in, it's browsers designed specifically to allow people to run programs on your computer without you even knowing. While they have been improved in protecting us to some degree, their very nature means that hackers/crackers have an invitation they shouldn't have.
