Question about WinXP registry entry

Windows XP Home SP2
I've been cleaning malware from this PC, and I was more or less done and I decided to look thru the registry RUN keys just be sure they were clean, and in the process, I found this:

Registry Key:HKLM\Software\Microsoft\Windows\Current Version\RunOnce
Key Value: OOBEDDDemise REG_SZ cmd /x /c erase C:\WINDOWS\System32\oobe\msoobe.exe...

That is exactly how it looks, with the three dots after the .exe and everything. I know that MSOOBE is the Microsoft Out Of Box Experience and is usually tied in with product activation (I think). But what's with this OOBE Demise? and the the "erase" command? I'm pretty sure it's related to all the malware that was removed, but any more info would be great.
Thanks

 

It certainly is part of it. Maybe the installer? Runonce keys only run...once

Nuke it at any rate.

 

Yup. It was nuked. I'd just never seen anything that blantantly said "Demise" right in it! It was so obviously malware that I thought it almost too obvious, ya know what I mean?

 

Maybe the creator wanted to be a show off.
