yellow exclamation marks (code 39) on all usb devices

  1. Hi all,

    after lengthy searching and trying I wonder wether anybody here knows the
    solution to the following problem of a friend of mine:

    Acer Notebook with intel chipset, running XP pro SP3

    infection by trojan got via skype-bait-message with following unreflected
    click on link, causing browser (Firefox afaik!) to execute malicious code.
    Apparently healed by Kaspersky Antivirus software new version installed over
    existing one. No more messages about infection. Though not everything o.k.
    since some Kaspersky network connection has yellow exclamation mark in
    device manager still.

    no usb device works. All have yellow exclamation marks in device manager,
    code 39, (inexistent or corrupted driver).

    Tried and failed remedies:
    switching off power. deleting all usb-devices and letting windows reinstall
    them. deleting a certain "upper filter" value in the registry key of the usb
    devices (no apparent effect). Trying to update drive via windows CD or
    microsoft online update connection (didn't find driver better suited than
    existing and refused to replace).

    Thanks anyway for reading and thinking about it.
