(oops, didn't see that you already did that)

The WJView on startup will either be in the programs list under "startup" or in your registry.

If you are comfortable using the registry open it (using regedit on the "run" command window) and do a search for the filename, it should appear under HKEY_LOCAL_MACHINE/SOFTWARE/MICROSOFT/WINDOWS/CURRENT VERSION/RUN

Just delete the key containing the multiple running one.

Another possibility is that it's being started as a service, for that you'll need to go to your control panel, open the "administrative tools" window, then go to the services part and see if the WJView service is being started there, if so, just disable it.
