What product do I have

On the web site > Products, I see

Internet Security
Internet Security Pro
Internet Security Plus

When I hover over the tray icon, the bubble says
Internet Security Premium.

I don’t see that on the web page.

What do I actually have installed?

The software for all versions is the same.
The differences can be seen in this sticky.

Ah, that is clear. Thanks for the link. Sorry I didn’t see it before posting (I did look a bit, but obviously missed it).
