I installed avast home edition 4.6, but when I looked in task manager, it appears that this is still 32bit – not 64 bit? Doesn’t that make it a little slower than having it in native 64? The processor has to switch between 32 and 64 bit modes when switching threads among different applications, right? I’d like my computer to run as fast as possible, and I think this necessitates a native 64 bit version, right?
