Whenever AviraVPN will be updated, it will automatically install Avira Launcher in background, so I better suggest not to mess with it, trying to disable services/delete registry related to it, it will come back eventually. Dealing with Avira Launcher is like fighting against windmills. If you accept any Avira product on your PC, you should accept that Avira Launcher will be there as well. Also, with messing with it, you may break some functionality of updates for Avira products. I am a Avira's Beta user, and all I can say is that they are trying to improve Avira Launcher.
