Scanning secure web pages?

Does Avast Web Shield scan secure web pages for malware, etc.? The reason I ask this is that there does appear to be a proxy on a port 12443. That prompts me to doubt that Avast does scan secure web page inward traffic.

avast! does not scan https connection. It scans http.

If malware were to be downloaded via https… the file shield/deepscreen will handle it.

You failed to mention whether it’s a TCP or UDP port.
There is a difference.
