Avast has many compatibility issues with 64-bit

Such as what? Please specify and give examples. I'm currently running Avast! on all my OSes, both 32-bit and 64-bit, and I haven't had any issues whatsoever.

Some advanced features such as Boot Scan and Kernel Protection module won't work in x64

Norton will throw a fit if another scanner is active! Especially if it continually scan Nortons own files. It really, really hates it, as do many others.
I would just use Norton myself, but its your call.

However, as already stated, you should only run one active scanning virus program, regardless what you choose.

for secondary scanning:
Something like Malwarebytes, that only scans manually, is fine to run along side it however and Norton will co-operate with it.

I believe that norton has tried their best to make their suite as good as possible =D
Do you know their latest version includes jumplist support and integration with control panel, etc..
Also, I believe that this assertion is true: that norton's product is more optimized for 64 bit os, though I cannot back up that assertion. Since Avast is a free solution, they do not have as much pressure as a company like Norton.

I also agree that running two antivirus is horrible. If one of those two antiviruses is Norton, it's unthinkable.
I suppose the fact is: Trust Norton to protect your computer, or Trust Avast to protect your computer (though I would personally go with Norton). However, don't trust them if they are together.
