    this isnt A vs B thread :D
    i just wondering about how web scanner works..
    does it scan data stream (before file created) or scan partial file that downloaded into temporary folder/ using internal proxy ?
    i ask because i see different behaviour on some AV.
    eg. ESET will terminate connection and quarantine but Kaspersky & AVAST just terminate connection.

    You also have to consider the browser being used. Not all browsers play the same way with a web scanner.

    Not sure about ESET, but Kaspersky scans packets coming through ports (eg, port 80 commonly for web-traffic), buffers it (stores some of it in its memory), scans a little bulk of it, and then sends it to your computer - loop process.

    If malicious code is detected, terminate connection and kill buffered content.

    Sometimes why users see a short delay if the settings are wrong - "limit traffic caching time" or "buffering time".

    Yes. It scans the packets as they are transmitted through the data stream.
