Now the webprotection works against secure webpages.
I do not understand avast.
Could you be a little more specific? If you mean you are getting
alerts or blocks on web pages that use HTTPS then that is not
surprising or unusual. A "secure" web page - HTTPS - does not mean
that the page/site is free of malware. It just means that traffic
to/from the user and the site is encrypted, which protects against
interception of the data being transferred. Snoops can't read the
data if they hack the connection because encryption garbles it.
But that does NOT mean that what you are receiving is non-malevolent.
Malware can be transferred over a "secure" HTTPS connection.
