When I was using Bitdefender, it would find a conservative amount of "issues", Kaspersky is the same way. But I believe both still don't give any specific information on what it found and wants to delete. I had compared a BD Vulnerability scan compared to CCleaner and Glary Utilities. It was interesting what all 3 found (ran the scans one after the other). So I agree, unless you know what you're looking for, those utilities are overkill and you could cause needless issues if you enabled the auto delete.
