Large Norton 360 Files That I Wonder If I Can Delete

Norton 360 for Windows
1

I wonder if these older files are still necessary. They date from 2019 and 2020.
Both are:
DSP-N360-xxxxxxxx-SHPD-FSD52xxxxx
With “x” representing numbers.

Another file from 2018 is NSBUxxxxxxx-SHPD-FSD51xxxxx

What are these files? are they older versions of more recent files? do I need to keep them?

Thanks.

Those look like old downloaded installation files. No problem deleting them as they are for products no longer available.

They are gone. So far so good. Thanks.
