Hi My Norton Firewall, running under OSX 10.10.5, occasionally report some unusual files trying to access the Internet including personal *.txt and *.doc files. This seems very odd to me and I wondered if the system is infected and requires the re-installation of the OS. Also, Norton often does not start when the system is rebooted. Is there anything to worry about? (I've come across a similar forum thread in 2013, and wonder if there is already a solution for this and why the thread was closed.) Thanks.
