Now that Zemana has their anti keylogger in an x64 flavor I think its appropriate to compare the two since it wasnt previously possible in the same situation. I assume to do Windows KPP (Kernel Patch Protection) that both are limited in one way or another. However there have to be detection differences or module differences that one can do that the other cant. I personally love Spyshelter Premium on my Windows x64 Pro. It has a very clean interface, seems to be doing its job properly, and has an easy to use GUI and configuration. I cant say anything for Zemana. Anyone for or against either of them, experiences with either of them? Keep in mind we are strictly speaking about the x64 flavors, not their x86 counterparts.
