And the integrity of the msnmsgr.exe is important, too. Malware can
easily replace a existing msnmsgr.exe or simply create a new one at
another place (like Rbot did - especially if a user is over-
privileged.

To be sure, the OP should take sysinternals Process Explorer.

If he was using an overly privileged account that may not suffice, since
a rootkit may manipulate what Process Explorer gets to see. I would
recommend using RootkitRevealer in addition to Process Explorer. Even
better would be to boot some other system (Knoppix, BartPE, ... you name
it), get the checksum of the binaries in question and compare them to
the checksums on a known-good system.
