As i understand most antivirus today are compatible with 64bit systems. But mostly of them install in the x86 folder. Comodo IS 3.5 does not. It is fully integrated to 64bit systems. So my question is if every security suite in the world would be fully integrated into 64 bits systems.. Would they be more secure than those installing via the x86 folder. And what is the difference between those two ways to install?
