syminstallstub.exe installs Norton Security Scan and is bundled with Adobe's Shockwave Player. It is added as a startup item in the registry:

HKLM\..\RunOnce, SymInstallStub = C:\WINDOWS\system32\Adobe\Shockwave 11\syminstallstub.exe /partnerid=adobe /productlist=nss /staging=false /debug /delay=5 /tasktries=1

It seems if you do not unchack the 'install Registry Mechanic' option when installing Shockwave Player, Adobe dumps this syminstallstub rubbish on your computer. Isn't it time for a class action against Adobe to compensate us for all our time they have wasted since they first began? (But one has to commend the name ... adobe is a form of construction using a blend of mud and cow shit.)

...i still don't get what they expected to gain by adding their junk to the shockwave player... standard users won't notice or freak out, geeks will complain and do their utmost to get rid of the unwanted code AND give a bad rep to Adobe / Symantec for fooling around...
I liked your detailed explanation but in my opinion the main question was overlooked : WHAT DOES IT DO ???

It seems SymInstallStub has been added as "trusted"?

Just when I thought I found a solution for removing this rubbish.

@Stephen: Yes, files signed by Symantec Corporation have been added to the trusted list and appear in green in FreeFixer's scan result. I'm sorry that the web site does not yet reflect this. I need to make some code changes to the web site to have this issue fixed. I'll look into. Thanks for the feedback.

Anyway, there is a way to delete any file, even those that FreeFixer considers to be trusted. Please use this feature with care:

1. Start FreeFixer.
2. Click the Tools tab.
3. Locate the "File Nuker" tool.
4. Type in the full path to the file that you want to remove.
5. Click the Delete file button and follow the instructions.

Did this solve the problem?

I am trying to read up about syminstallstub.exe at 'C:\WINDOWS\system32\Adobe\Shockwave 12\
My wife had this on her xp machine, and I found by watching a realtime internet meter, and the task manager, that everytime syminstallstub.exe started up it would use huge amounts of internet usage. Since removing this file from the computer we are no longer using approximately 1GB of internet download per hour, which was happenning with it there. Is this a problem with syminstallstub.exe, or would it be caused by a virus that had affected that file.
I did not keep the file, just got rid of it, as I urgently needed to reduce our downloads.
No antivirus or malware problems picked up that there was a problem, but having deleted the file, the problem has gone away permanently.
