Not having educated myself on the ins and outs of the various security suites, I have some questions:

From a purely functional POV, does native support for X64 really matter? Or more gently - is there some aspect of a 64 bit OS that prevents, or hinders a 32 bit app from performing it's job? Is there some inability inherent in a 32 bit app preventing it from doing it's job effectively when it's running on a 64 bit OS instead of a 32 bit one?

I know that a native 64 bit app would be the choice for a 64 bit OS because it should run best. (I say 'should' because well written 32 bit code is always going to be better than garbage dumped into a 64 bit compiler)

Anyways - I would simply like to better understand if there's some 'hole' if a given user is running a 32 bit Anti Virus suite on their 64 bit system.
