Hi agonizingfury,

Do you have the DLLHOST.EXE here?:
C:\Windows\System32\Wins\DLLHOST.EXE 

If so, it's a virus.  
(C:\Windows\System32\dllhost.exe is ok and not a virus)

Detailed instructions for getting rid of it:

Hummer,
  yes, that was it. Welchia. Don't know why her virus checker didn't
find it. Please post this as your answer to receive credit for the
answer.

Thanks Again,
Agonizing Fury

Hello agonizingfury,

Thank you, I'm happy to hear that I was able to solve it. As far as
virus scans go, I think it is a good idea to use at least two
different programs on a regular basis. For example, I use the free
version of AVG antivirus for my day-to-day monitoring and every few
months use HouseCall just to double-check. HouseCall is very thorough
and often finds something when other programs haven't.

HouseCall:

AVG:

Again, thank you - here's hoping your friend's computer stays
virus-free.
