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)?
On startup, the Trojan is started via registry entries. Since it is a DLL, it needs rundll32.exe to start. When it starts, it hooks itself into (I think) *every* running process on the system, so you can't actually kill it without shutting down the system. It checks the registry keys periodically (configurable, I believe), and if they are missing, it adds them back in again.
