Please tell us what your operating systems are onPC #1 (the one that Norotn is OK on) and PC #2 and #3 which Norton is not OK on.
Also do you have any other Antivirus, or anti-malware installed on any of the systems? Is Windows Defender enabled?
The more info you can give us in regards to system configuration etc will be helpful.
