Quick Question

The Channel 4 on demmand program constantly runs the Kservice.exe process, Which also connects to the internet and uses bandwidth for something, everytime you boot even if you disable the start up entry. So i have resorted to killing it with D+ after everytime i boot.I didnt kill and block because the process needs to run for the rare occation when i use the 4OD app. I was wondering is there away to block the proccess but unblock it when needed??? Would the “My blocked Files” do the job??
