I find it hard to swallow that a vendor like Aladdin can write a filesystem driver that filters USB requests to encrypt data on the fly using documented interfaces, that a vendor like CA can write a driver that filters all incoming TCP connections using documented interfaces, and that a vendor like PointSec can write a driver to intercept filesystem calls using documented interfaces; but somehow McAfee can't get it together to grep the filesystem for malware without "going commando" all over Windows Vista in a way that requires them to rewrite the kernel. WTF?!
