Windows Vista Security

Following on from my previous post supporting Microsoft in locking down the Vista kernel to keep other companies out and all the noise from anti-virus vendors there is a bigger issue underlying all this.

If software vendors cannot get inside windows, that in principle means that virus writers can't either. So if viruses and security software are successfully locked out of Vista what is the problem? Surely anti-virus companies only want to be saviours and protect our critical computers from damage. They couldn't possibly be wanting the system to be opened up so viruses can infect a system so they can sell a product to remove the viruses?? Nah - Im being silly now :)
