G'day paulderdash - You may want to consider that what Adguard is doing is actually a MITM attack, and as such is introducing a security hole in your system. Avast--and almost all security software--is also doing it now.
The Adguard Certificate will actually replace whatever Site Certificate is supposed to be presented to your browser. Read Security Week
for more detail.
FWIW, I and many others disabled Avast WebShield for this reason, and I'm sure--with no research to back it up--that users of other AV systems have done the same. IMHO, no security system needs to fiddle with TLS which is our prime protection against MITM.
