Close the editor and disable root and you are done! (For android).Save the file (how will depend on which editor you use).Copy and paste the domain names, (taking care to not overwrite stuff already in there) exactly as from here, the ones above have formatting.Tap the file and open it with the built in editor in File Manager (Check the set it default box).Tap the check box for Group under the Write column ( Example pic here).Locate and long-press the hosts file & wait for the menu to show up (you can search).These will be the domains we will be blocking: Here we are going to be editing the Android & Windows Hosts file, to disable Nox App player from phoning home to dodgy domains, delivering encrypted payloads that could contain sensitive data for all you know. Firstly click on the System Folder, then app, now look for a file named Launcher_X.X.X_en_signed.apk and click n' hold till a context menu pops up, select rename and it to 'Launcher_X.X.X_en_'.Now open up 'File Manager' not the 'ES File Explorer', it should come with your installation by default, immediately upon launching the app, you should see the System folder near the bottom.Install your new Launcher from the Google play store, my preference and recommendation is the Evie Launcher, after installation you should see it prompt you to change your default launcher, you must change it away from Nox.Enable Root Mode on Nox, by clicking on gear icon then checking the Root Startup box, before restarting.In this step we are going to replace the default Nox launcher with the Evie Launcher or one of your own choice. Note: DO NOT INSTALL ANYTHING LATER THAN NOX 5.0.0, install later versions at your own risk, find a torrent if you can Step 1.

(As /u/therealhughjeffner said: ' This thing, calls home more than a homesick kid at summer camp') Nox App Player is free app that whilst it comes with benefits, it needs a bit of work to make it safer and quick. You can definitely try this on lower versions of Nox but no guarantees. This will be a detailed step-by-step guide on how to disable all the spyware, background app advertisements/automatic app installs and make your emulator faster and more stable.
