How Are Ads Running On My Computer?

    I can't work out where popup ads are coming from. I've run Housecall, NAV,
    Ad-aware, Spybot & have Zonealarm running (plus NAV & XP firewalls).
    Although I'm logged on all I've done in the last few hours is to kill the
    popups & send this post. Apart from that my computer is at Google's homepage
    & I haven't been doing anything. I can use a Popup killer of course but that
    doesn't explain how the ads are occuring.
    I have obviously inadvertently downloaded something that is generating them
    but how can I find it when all that stuff that I've already run doesn't find

    I'm guessing that these are Messenger pop-ups.
    You should block ports 137-139 (NETBIOS) in your
    firewall, as these are the ports that the Messenger
    service uses.

    To prevent Windows Messenger Service from starting
    automatically, open the Services panel by typing...

    services.msc /s

    ....into the Start / Run box.
    In the right-hand pane highlight 'Messenger'.
    Right click and choose 'Properties'.
    Click the 'Stop' button.
    From the 'Startup Type' drop down, choose 'Disabled' or 'Manual'.
    'Apply / Ok'.

    The messenger service listens on port 135 and some other dynamically chosen
    port in the range starting at 1024. That second port will be slightly
    different for each machine. While that port is typically around the valid
    1040, it can be virtually any port. Ports starting at 10000 have been seen.

    The Messenger Service uses NETBIOS to communicate.
    The listening ports are irrelevant.

    One can block port 135 as well and leave 137-139 and 445 as is not blocked
    and the messages will not make it.

    So I don't now how some machine on the Internet that's using the Messenger
    Service is getting to unprotected machines is doing it with the Messenger
    service not listening on port 135. That's to my understanding

    The link down at the bottom talks about the ports including port 135.;[ln];330904

    All that is necessary is to block NETBIOS (137-139) broadcasts,

    We'll agree to disagree and leave it at that. :)
