I contacted Norton customer support via Live Chat at and gave them my Windows OS and Norton product names (past and current) and they were able to provide a list of possible registry entries and files/folders left behind by the NRnR tool that I could manually delete.

I used Norton for several years on a Vista SP2 computer and found that a 'Remove Only' wipe with the NRnR tool did not do a great job of removing remnants of previous Control Panel | Programs and Features uninstalls, especially for my older Norton products. 'Remove Only' mode does a deeper wipe of orphaned files and registry entries, although it (deliberately) leaves behind a few traces that can be removed manually. If the 'Forced Uninstall' option of the trial version of Revo Uninstaller Pro can't remove the last traces of Norton then be sure you run the Norton Remove and Reinstall (NRnR) Tool in advanced 'Remove Only' mode as instructed in the Norton support article Download and Run the Norton Remove and Reinstall Tool for Windows. 'Forced Uninstall' is a Pro option so it needs to be the Revo Pro version - but if you don't want to purchase Revo there is a 30 day trial of Pro which should be plenty of time to do this job. I'd try using Revo Uninstaller which can find and remove such leftovers.As you have already removed Norton and Malwarebytes you will probably need the 'Forced Uninstall' option in Revo. You can also achieve the same as 'Forced Uninstall' with Revo Free, it just takes more steps - Once you have Revo Free installed then re-install the offending app and use Revo Free to uninstall it again, it's just more faffing about having to do that re-install/uninstall). I'd try using Revo Uninstaller which can find and remove such leftovers.Īs you have already removed Norton and Malwarebytes you will probably need the 'Forced Uninstall' option in Revo. Usually using the security app's own removal tool rather than just uninstalling gets rid of everything, but even that sometimes leaves things behind. There are often leftover registry entries and files/folders following an uninstall, and especially from uninstalls of Antivirus/Antimalware apps that have self-protection.
