All comments about penusa.dll:
Freddo Used with MS Office
Faith This exe allows me to switch between Germand and English keyboards.
Stephen Somehow associated with Microsoft Office Publisher. I was hit by the Israel Worm recently but a deep clean removed most of (but perhaps not ALL) of it's components. If you have been wormed lately, see if Office Publisher seems a bit more...menacing.
