Anti-Virus and Windows Vista

From Ben Farthi:

In my role as the head of Microsoft security, I personally spent many years explaining to antivirus vendors why we would no longer allow them to “patch” kernel instructions and data structures in memory, why this was a security risk, and why they needed to use approved APIs going forward, that we would no longer support their legacy apps with deep hooks in the Windows kernel — the same ones that hackers were using to attack consumer systems. Our “friends”, the antivirus vendors, turned around and sued us, claiming we were blocking their livelihood and abusing our monopoly power! With friends like that, who needs enemies? They just wanted their old solutions to keep working even if that meant reducing the security of our mutual customer — the very thing they were supposed to be improving.

Anti-virus programs remain a problem in terms of the attack surface they can open up. This surface, combined with the failure of many products to effectively identify and act on malware signatures, means that consumers tend to put far too much trust in products that often function poorly at best.
