Useful thing the Statistics feature. It quickly and easily tells you what is and what is not happening in Avast. I have a copy of Opera 12.17 on my system. OK, I know it's legacy and obsolete but it also allows me to discover that not only is scripting not filtered (expected since Opera is not on the script filtering list) but also that Opera 12 https traffic is not scanned and I didn't expect that. I mention this in case others might be under the same misapprehension as I was that https traffic on all browsers, new and old, is scanned by Web Shield.
Nothing is said in the Web Shield Main settings window to qualify the scope of enabled https scanning.
