Couldn't get a good decompilation of this file..
Most decompilers just seem to sigsev on it.
Some did get some info out of it (mostly obscured)..

Did get something out of PEDasm
attached is the output (in a zip)..

It's not all that usefull with a copletely stripped binary like this..

Perhaps someone with IDApro or something can get more out of it..

(F-Secure detects the worm btw)
