Avast save a NEW network profile with a number once my laptop connect to my mobile hot spot.
I tried to use avastclear to completely uninstall Avast and reinstall Avast, but they are still here.
The list is so long that the GUI is laggy.
So, I want to know whether I can clear the network profile list or not.

I think it grabs it directly from your Windows network list. Try going to an old network that you don’t need to connect to anymore and right clicking on it and clicking “Forget network” and see if it deletes it from the Avast list.
Hover your mouse cursor over the network you wish to delete and a garbage can appears (same location as your screenshot).
Edit to clarify response.

Works for Windows 10.
If you’ve got passwords, removing any stored network will delete your passwords too.
I tried to forget the network in Windows settings. But they are still here. What should I do now? 
It works. But the networks are still in the list of firewall. And there isn’t any delete button.
Umm… I tried that. And purged all the networks. But they are still in the list.
Did you reboot after clearing?
Yes, I rebooted my computer. But they are still here
What hotspot you use?
Access to a wireless router?
Hotspot of my Android phone
Issue could be with your Android Phone hotspot.
Steps given above should have cleared all Windows networks from your system.
Umm… These above steps cleared all the networks in Windows. But they are still in the network list of firewall of Avast.
Reread reply #2. If you don’t see the trash can you might try a Avast repair. You mustn’t be connected to the network when trying to delete it.
The trash works but the networks are still in the network list in the firewall.
Post a screenshot.
Please see screenshot. How to delete recent network items?
You are looking in a different place to the Image that Lano posted.
Avast UI > Menu > Settings > Protection > Network Inspector > List of monitored networks.
Yes, you’re right and I know it’s different.
But still I can NOT delete these items here. Any solution? Thx.
You don’t say ‘what you have done’ to try and get rid of them so it is hard to make any suggestion.
Do you have any clue what the entries in your Firewall Networks image were, open the Show settings and see if you recognise them and or should they be trusted. I have lots of entries in Firewall Networks some unknown and some known.
However, my list of monitored Networks is very small two or occasionally 3.
