Hi, recently closed Steam then around 10 seconds later I get this

", is trying to access C/Windows(etc)/taskmgr" That isn't the exact path I was given but it was certainly trying to access task manager.
I have an image of the Program Control section here:


Basically there's no information about the process, just that it's 0kb.
Wondering if anyone knows what this could be? I have run full checks with AVG and Spybot, both up to date but have found nothing.
Thanks for your time.
EDIT: Also, forgot to mention that as soon as I denied it access, Explorer.exe (Desktop icons/menus etc) basically shut itself down and the computer went into sleep mode.

Operating System:
Windows Vista Home Premium
Software Version:
7.1 (Vista)
Product Name:
ZoneAlarm Antivirus
