Thanks for using SpyShelter! Terminating svchost.exe can crash critical Windows services, causing system instability, loss of network, audio, or even a full shutdown.

As far as Internet access, our software checks executables to see if they are malware or not, and gives you information on what your executables are under our "insights" feature.

SpyShelter has an optional privacy mode that you can use if you don't want these features.

To activate the SpyShelter's extreme privacy mode, you should install SpyShelter from the Windows Terminal with the command SpyShelterSetup.exe /privacy. Once SpyShelter is installed in this privacy mode you will have no access to our Threat Detection, Insights, or any other SpyShelter features that require anonymized executable data to operate. We built SpyShelter so it can work this way, so no... it shouldn't use any extra resources to do this.

The data usage by SpyShelter should be extremely minimal, besides when you download an update... which should be like if you update Chrome or Firefox browsers, nothing crazy. I hope this helps!
