Norton Antivirus 10.2.1. for Mac Snow Leopard

Hi

 

Have just upgraded mi Imac for Snow Leopard and installed my antivirus 10.2.1. with several problems. Is there a patch for making it work or what ? Tried to uninstall it again - but I can't get rid of it all - how do i do it the right way ?  Tried AppZapper with no luck

 

Thanx in advance
