I am disturbed about this icloudCKKS.exe. I discovered it was preventing my pc from restarting and decided to look into it. Its very disturbing when I found out it listened in one time. To my knowledge I dont know how it came to be on my system. I will be removing it. I dont trust Windows any more.

May I simply just say what a comfort to uncover someone who actually understands what they're discussing on the web. You certainly understand how to bring an issue to light and make it important. More people really need to look at this and understand this side of the story. It's surprising you're not more popular since you definitely have the gift.
