So, I have an MSi Z87 GD65 Motherboard, which came with Killer Networking drivers for the Ethernet hardware. I had problems with it when I bought it, and so I eventually I just used the bare drivers as I heard the Network Suite could cause BSOD's and lag spikes when playing games. Problem is, I recently updated my drivers, and am beginning to have harsh ping (800+ms) when I play games. I checked, and even though when I search for the network suite from the start menu nothing comes up, it still appears in the list of installed programs. The problem is I can't uninstall it. Every time I try it says "cannot complete installation" and stops. I downloaded the bare drivers from MSi Live update, but I can't run the setup because it says I need to uninstall Qualcomm Atheros Network Suite. I've heard of KillerCleaner64, but I can't seem to find it anywhere, and on top of that, I'm not sure how to go about uninstalling a program that will refuse to uninstall.
