Ok so I had Norton AV installed and wanted to switch to Kaspersky AV. I clicked the Kaspersky setup and it prompted me to uninstall the current AV installed automatically. It asked me to reboot, but at startup, ask me the same thing again. The cycle repeats and it seems like Norton is still installed on the system. So automatic uninstall of Norton AV using Kaspersky was apparently the wrong thing to do. It did a very messy uninstall and Norton AV wasn't on the Add or Remove Programs list anymore, but Norton WMI Update is still there. And when I prompted to uninstall Norton WMI UPdate, a prompt states that a product that is still using the product is still on the system. I check the Norton AV folder in Programs Files and it seems like most of the files are still there except the uninstall file, if it ever had one. So using Winpatrol, I removed all Norton AV startups, IE Helpers and Scheduled tasks, or at least I think so. In the Active Tasks, I can see NAV related tasks like NPROTECT.EXE, SYMLCSVC.EXE, SYMWSC.EXE running but I cannot kill them. I even went drastic and chose Delete on Reboot and still they did not stop after restart. So now I'm stuck with a crippled AV with no idea how to cleanly uninstall, and I can't install a new AV or even the same NAV since it's state that there is a newer version already installed and I need to uninstall it. It was probably very stupid of me to use the Kaspersky uninstall option instead of manually uninstalling NAV using Add Remove. So can anybody offer any solution or remedy to this problem?
You could try deleting the Norton folders from your computer. Once you do that, then you will need to run Regedit and manually remove ALL of the Norton AV and/or Symantec references from your Registry. Need to be extra careful when you go manual. There may be some uninstall programs you could try to remove Norton. There may be some registry cleaners you could try to remove the entries. I don't know any specific names to recommend. I used Norton before and have switched to AVG Free. Had to manually remove Norton. Even the Add/Remove under windows did not work for me after Norton started giving me problems that even the Symantec "experts" could NOT fix after spending days on the telephone support (my dime).
Thanks for the suggestions. I went and disabled the NAV Services that automatically start up and delete the NAV folder in Program Files as well as in regedit and that seems to work well. Now everything uninstalled fine and I can install my new AV. I'm still not sure if that got rid of everything Norton related though but at least I got my other AV installed.
Regcleaner might do the trick IF there would be anything left : http://www.worldstart.com/weekly-download/archives/reg-cleaner4.3.htm
