PYCTYSSKE service ??

This service was running on Windows XP Professional. I was shocked when I
noticed it in the Computer Management mmc snap-in. The executable was found
in C:\Documents and Settings\LOCALS~\Temp.. The application that I found was
Root Kit Revealer from Sysinternals renamed as PYCTYSSKE.exe. The CA
certificate showed that the object did not have a valid digital signature.
Valid from 4-4-06 to 10-4-07
! Key Usage Digital Signature non-Repudiation (c0)
! Basic Constraints Subject type =CA, PathLength.....
I use an account that belongs to the users group and very rarely log on as
Administrator. The application was installed on an account with Administrator
rights. I found a log file that it made in the Temp folder as well.
Google fails to query a result and I am without an explanation.
Any clue??
