I am using Firefox with addons Adblock plus and NoScript. I am also using Avast File and Web Shield and I wonder does Web Shield during the scanning of web page also scans ads and scripts that are blocked my these two Firefox addons.
It scans the http traffic. The firefox add-ons are local files and aren’t scanned by the web shield. NoScript only stops scripts from running, if that script is embedded in the page then that is a part of the actual page content and would be part of the http traffic coming down to the browser, that would be scanned.
AdBlock+ blocks ads, etc. so they wouldn’t actually be downloaded for display on the browser, so there would be nothing in the http traffic for the web shield to scan.
I have NoScript and AdBlock+ and no problems.
