Avast Cleanup shows # 'PB' selected in Firefox cache; what are PB?

Avast Cleanup Premium 22.4 Build 12696.

Browser data section shows: Mozilla Firefox - Cache, 26.7 PB selected.

What does PB represent? I think of Peta Bytes, but that can't be it. Is it a typo in the software?

I get this message too. I contacted support about it and they gave me the stock answer "We would like to connect with your computer remotely and have a look". (Like hell you will).
The implication is that there is 86 petrabytes of junk in my system, but my system is not capable of storing 86 million GB of data, so it seems like a fault in the software.
