How can I identify the cache if I see its name? One belongs to malware

If Device maintenance app is launched in Samsung S8, after pressing Clean Now button, storage cleanup briefly shows different apps, storage space of which is being cleaned:

System cache OneNote TopBuzz 

I know that the last one is a malware and is not present in my list of apps, but how can I find out to which app it actually belongs? No antivirus which I tried so far reported this as a malware. But maybe there is some system analyzer which shows similar cache ownership like the above app, but with more details?

(Or maybe there is another method how to find origin of that TopBuzz symptom.)

The phone is not rooted.
