Constantly getting permission issue "can’t delete"

I think this app is used only to show you advertising of other apps this company makes. I have to date deleted 2 apps out of over 10 attempts. The majority of the time I get a statement about a permission issue, use Finder to goto the app to delete it…duh…thats what your app is for. If you cant write an app to do what its suppose to, why bother…unless its a chance to slip in a bunch of advertising for your other apps???
