    if the ips is picking something up it may be something to watch out for.  make sure your systems are all updated before disabling.  routing through http proxy is good as long as you ahve a/v on and you have the block spyware commuications enabled as well.

    That appears to be a new IPS rule, it has only started showing up seriously in the last couple of days.
    I am seeing the same rule applied to ff on my MAC.
