Notification overload.

My credit card company emails me saying that they have emailed me the statement!

NOTIFICATION OVERLOAD

I got a new phone, and there is an option in the settings to disable notifications for specific apps. Of course, to prevent overload from apps.
The problem is that the apps that actually spam me:
Bloatware "antimalware" wants to be activated (I have eset on my phone and thats probably better than a random bloatware) and Samsungs integrated file manager "My files" (I have es installed anyways and its better than the bloatware. Im sure I use it.)
Their notifications just cant be turned off fully. Instead I only have the option to "hide them on lockscreen".
Nice, except the lockscreen is the only place my notifications actually dont show up. Even when I want to, it just doesnt work.
The teams making apps should actually read the docs of other projects, as this is just massivly uninformed development.

Is there a way to clear all the "comments on a rant you commented on" wo clearing "has commented on your rant" notifications?
