If you are talking about this dropper - "setup.exe - 7/43 - Sunbelt - Packed.Win32.Tdss.ae (v) - MD5 : 8d73a4cd281f178ac7896d54d7923728"
it is a classical TDL3 and it works well under VMWare with XP SP2:

Yep, I tried one with SHA1 hash e3f9d41825ca05b96dcab8491256faffe2c2aae2 (dg.exe).
It works on Windows x64.
So, this means this malware is still under active developement for Windows x64 (not dead)?

If you block spoolsv.exe to install its drivers on x32 TDSS also wants to have direct disk access (MBR) on this OS as well. Is this new?
Then it shuts down Windows. Can anybody explain how it's doing this? The VM just closes rapidly and OSSS HIPS can't detect any attempt to shutdown Windows or to log off the user.
I dunno if it tries to install a bootkit or just to mess up the MBR, at least Windows doesn't boot anymore after spoolsv.exe had direct sector access.
