RE: New Trojan

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.
