    An option; restrict rights for
    HKLM/Software/Microsoft/Windows/CurrentVersion/Run so that new keys cannot
    be created, by anyone. Remove the key used by the trojan. Reboot, and
    return permissions for that part of the registry to prior settings.

    A thought: considering that this is a proxy trojan, could it have any
    relationship to the alleged instances of a Polish company offering stealthed
    spamming services (and god knows what other forms of anonymization)?
