Avast HTTPS Scan gone wrong when changing time zone.

Avast HTTPS scan giving wrong CA after I change clock and time zone.
It was working fine prior synchronize with ms-time, though.

Seems like good ol’ bug still exist.
I’ve uninstall the software already, about to re-install.
Will report if there is any further problem.

What happens if you disable HTTPS scanning?

What exactly do you mean by “wrong CA”? So, you had the time incorrectly set, fixed it - and a problem appeared?
Does the problem appear on a specific website, or on all sites?
