Have a look at these pages. Personally I would uninstall and then disable as per the first link.

Thanks for the reply JOcean. I'm just venting more than anything as I go straight to find smartbyte to uninstall, almost by muscle memory now after running a Dell update. Didn't know you could completely disable reinstall. Thanks 👍🏻

Glad to help out!

Hey guys,

Official SmartByte support here.

SmartByte should not reinstall itself after it is uninstalled. We see reports of this, however. If you find that SmartByte reinstalls itself after you uninstall it, please contact us here - http://support.rivetnetworks.com/submit-a-ticket/ - so that we can get some information on you that will help us find the cause of it reinstalling. We believe that SmartByte when updated and used with a current network adapter driver, will improve your experience. However, we do not want users to feel like it is forced upon them!

I installed the SmartByte application on my 7567, again and it seems to be improved from earlier versions.  I have not yet done extensive testing, but I have not gotten the static even with system sounds as well as str*eam*ing.

I had uninstalled it earlier and no attempt was made to reinstall as far as I can tell.

It's an inspiron 15 7577. 

What system do you have?  Some systems are coming with the Cinema sound/display etc.  If it were one of those, the Smartbytes might be reinstalled as part of that.
