Situation:
You installed Norton AntiVirus 2004 and restarted the computer. Norton AntiVirus does not start when you double-click its desktop icon or its icon in the system tray, or when you try to start it through Windows Start. No error message appears.

Click on the lind and see the article for the solution.

Encountered myself many times. I always found that if a LiveUpdate did not fix, uninstalling, cleaning out registry, and reinstalling would (sometimes).
I use many registry cleaning programs to do the job. I do not have my registry list right now, but try doing a Google on "registry cleaning software" or something of the sorts.
Or try uninstalling/reinstalling first.

Hi

I have also had this/similar problems several times. If you uninstall the program make sure that all elements of the Symantec package are uninstalled, including LiveUpdate. Go through the list in Add/Remove programs to do this.

Also, when you reinstall, make sure that only essential (Microsoft) services are turned on. I recently had a problem with Norton GoBack, and disabling unessential services during installation, then re-enabling afterwards solved the problem.

Good luck
