Uhhh…I don’t mean to quibble, but I’ve been running Avast and Thunderbird for over a year, and Avast did set up Thunderbird…at least until the latest revision of TB.

I tried the manual setup, and when I asked TB to get mail, it told me it couldn’t connect to the 127.0.0.1 server…

And yes, TB uses POP3…
