I was wondering whether if it's stable when installed in XP 64 Bit Edition? Currently I've not installed XP 64 yet but I want to make sure before I does that. And how do I know currently which version of Norton SystemWorks or Internet Security are make to be compactable with it? Does the latest 2006 support 64 Bit?

Thanks alot!

I personally wouldn't use norton internet security myself, but I do believe they make a version for x64.

I see... So what other software you recommend?

I use avast antivirus.

I still can install back my old Norton products right? Since it will automatically install in the correct Program Files folder... Think still should be able to work.

Well not exactly. You can't run any old antivirus program on 64 bit windows, it has to be compatible. I don't think norton internet security is compatible with 64 bit windows. Avast is fully 64bit. But for norton I think you need the norton corporate version 10 which is compatible with x64.

Hope that makes sense.

Hmm... Seems quite hard... Anyway, thanks alot, dale5605!
