There is something wrong about https scaning

I copy a certification from trusted root certification authorities to untrusted publishers, but don’t delete the one in trusted root certification authorities. The brower tell me issuer is avast! Web/Mail Shield Root rather than avast! Web/Mail Shield Untrusted Root when I open the website.

You didn’t moved it, you copied it.
That is why the trusted one is used.

Yes, but, chrome will warn you if disable https scanning

Hi, we’ll check this. Thanks for reporting.
