MacOS Big Sur, Monterey and now Ventura

Every time I reboot the Mac or stop/start AVG it will try for 5-10 minutes to connect to a network resource (old Mac in this case) that no loner exists and hasn't for some time.

I have tried uninstalling AVG and using cleaning tools to remove every possible scrap of it I could find. After doing this, I can reboot repeatedly with out the error occurring.

However, as soon as I reinstall AVG, it starts again. Almost like there is some config file or something buried deep somewhere with this entry in it. I have even searched the entire drive for the specific text of the name of this device (FYB7 in this case-see pic).

This is the error I get

User-added image

I hope that image loads!
