Question : cannot install xp updates--manual or auto

Just upgraded a PC from XP Home to XP Pro and cleaned it of a lot of critters including a nasty case of Virtumonde.  Tried to install MS XP updates in both manual and automatic mode to no avail.  Used all the tricks listed at http://support.microsoft.com/kb/910359 and got a single error message during:
 
At the command prompt, type the following commands, press ENTER after each command, and then click OK every time that you receive a verification message:
regsvr32 wuapi.dll
regsvr32 wuaueng1.dll
regsvr32 wuaueng.dll
regsvr32 wucltui.dll
regsvr32 wups2.dll
regsvr32 wups.dll
regsvr32 wuweb.dll
      
I got an error message in CMD stating "DllRegisterServer in WUWEB.dll failed.  Retrun code was 0x80070005."

Tried it twice after a reboot.  No good.

I have kinda run up and down the hits on Google search but don't seem to be able to find anything that works.

Any ideas?

Answer : cannot install xp updates--manual or auto

No help for the update issue, BUT... if the machine had a nasty virus, I would get my data and re-install.  There is no real way to be totally sure all of the tentacles of a virus have been removed.  Once its been compromised, you can never be sure again.  Just my 2 cents.
