-- Jump to "My question" to skip the rant..

I ended up here after having fun with my tv for a while and then connecting it to the network.
The "Smart" (..) Hub was next to unusable, dog slow. I installed a couple of apps, 3-4 maximum. Those worked fine: One example is the TED app.
Now, meanwhile I connected a 'Samsung account' with my box and for reasons I cannot understand the thing updated the smart hub, updated the smart hub, updated the smart hub (yes, three times) and during this last update it started saying 'installing application 1/26'. What??
So, I bought a decent tv, the first connection to the network loaded it with crap, dung, bull... - with no way to remove it. Samsung Support? "Unfortunately you cannot remove these applications". I wanted to lynch the guy on the phone or return the tv. A temporary solution existed though: Disable the 'Samsung account' and reset Smart Hub. Now I have not a single app installed, but at least the garbage is gone as well.
-- "My question"
Is there a way, any way to modify my tv to use the smart hub thingy for apps I want, while being able to remove every piece of junk these braindead people throw at me? A 'delete protected app' feature? A 'don't install stuff I didn't ask for and would throw that tv out of the window for in the first place' setting?
If this is totally impossible that's cool to know as well. I've bought the set not even a week ago and would return it as defective to the store in that case. I just cannot wait a lot longer before I've to decide.
Can you help? Any insight?
Thanks
