✔ Best Answer
NSSstub.exe is Norton Security Scan executable.

You may have aquired it in two ways.

The first one is by installing Norton Security Scan software.

And the second one...

It comes packed with Adobe Shockwave v11.0.3.472
which was released on January 27, 2009.

Here is a screenshot from the installation process:

So, if you didn't unticked "Include Norton Security Scan"
you got it installed on your PC.

This tool won't do you any harm since all it does is scans
the computer and identifies if there are existing viruses,
worms, spyware, unwanted adware or Trojans residing on it.

But if you want to remove it, you'll have to do some work.
Removing this thing can really be a pain since it tends to
reinstall after you reboot you computer.

To completely remove it from your system you should do the following:

Uninstall Norton Security Scan via Add/Remove Programs:

    Start -> Control Panel
        -> Add/Remove Programs (Programs and Features in Vista)

Delete the NSSStub.exe from the scheduled tasks:
    Start -> Run -> type "compmgmt.msc /s"
        -> System Tools -> Task Scheduler -> Task Scheduler Library

Delete the NSSInstallation string from RunOnce registry key:

   Start -> Run -> type "regedit"

        If your system is 64-bit:
