Hmm, in reality you have absolutely no way of ensuring that when they are not "running" that they are not conflicting. Even if the actual process isn't appearing in task manager, it is still possible they do things which conflict, due to the installation process etc. This is why you can run into issues where people install a new product and it drags the system right down, it's because the old security product didn't properly remove itsself out of the OS.
You're probably going to be OK given the products you listed, andit obviously does run fine but, personally, I wouldn't try it because of the risk it would introduce instability which cannot be predicted.
I wouldn't do it on a production server put it that way
Out of interest though why do you feel you need to have so many products installed? Spyware doesn't force itsself onto the PC, you generally accidentally download it, if you are so concerned about that then just be extremely careful about downloading executables and run just one product.
The only thing those products detect surely are tracking cookies?
