Thank you Peter and Planet very much for your replies!
I hope I am going to have time to deal with them, but part of my problem is I am so busy that I just wanted an antivirus/firewall that supposedly was better integrated with/designed for Mac OS so that I can 'just quickly' do stuff on my laptop! (as apparently the reviews I read had found. I now wonder if those reviews were v5 rather than v6…...) and currently I have to factor in the possibility that I have to deal with some ESET generated problem just to do normal things. So I may not get time to pursue this further until after Christmas/New year.
Before I switched from Norton, I used the uninstaller to get rid of Norton, so I am not trying to use both at once. And in any case, the demo version of ESET worked fine for the trial month. It is a bit of a rip-off if you are not really trialling the thing you are about to purchase when you think you are.
Regarding the wifi setup, I used whatever the mac default method (in OSX 10.8.5) is to connect via wifi to our home modem, so if that is Airport then I take your word for it. But I don't actually think that connecting to the home modem via wifi is the problem because I was able to print a document at the same time that Safari was not connecting to the internet. (by that I mean that refreshing the google home screen in safari came up with a grey mac screen stating that i did not have internet connection, and no other websites were opening either) so it took me a while to figure out it might have been ESET. I thought at first that there was something wrong with the ADSL2 connection external to the modem. But the problem was corrected as soon as I unchecked the red block on the ESET 'public' wifi rule! (My macbook pro talks, via wifi and the netgear home modem, to our printer, which runs off our home desktop PC which runs windows7.)
As to whether I would have cancelled a query to define the home wifi as ‘home’ zone, I am almost certain I would have taken the opportunity to define it as ‘home’ and not dismissed, but I cant actually remember at what point in the procedings I was given the question to define it as ‘home’ zone, so I cant be absolutely certain, but I do remember defining it as ‘home’ at some point, when prompted. And when I was trying to figure out what was getting blocked I saw a screen under Firewall that stated "Profiles used on Network Interfaces / WiFi: Home "
Which then prompted me to find the rules and as I poked around and discovered the other zones for ‘public’ and ‘work’ I noted that there were no red blocked rules for either ‘home’ nor ‘work’ but there was one rule blocked for ‘public’ and that just happened to have the same name as the event in the log that was denied. So when I unchecked the box that selected that rule, the internet was immediately restored. This made me suspicious and I wondered whether there was some secret wifi connection going on that I was unaware of, but you would know whether that is possible better than me. I have never logged into any of our neighbors wifi if ever it has popped up as visible. I have logged into relatives wifi when I’ve visited them, but that was when I still had Norton and I defined those as ‘travelling’ or something similar. I forget what choices were available in Norton.
Anyway, currently I have allowed as new ‘home’ rules quite a lot of connections in and out and I followed your advice and put it back on automatic. Now it seems to be not preventing me from accessing the internet anymore and it seems to not be hanging itself trying to update through a blocked connection any more. So it is annoying that I had to go through that process, but it might have resolved whatever the essential thing was that everything else was log-jammed up behind.
The main problem now is that even though the smart scan I kicked off yesterday says it was completed, if I open up the log, it didn’t scan very many files compared even to previous interrupted scans (although they were probably deep scans??) and there is a long list of files there that all have a [4] at the end indicating that “Object cannot be opened. It may be in use by another application or operating system.”
The trouble with that is that I deliberately closed all my open apps and kicked that scan off when I didn’t need to use the computer and some of the files are for things like Canon scan and Preview and other software that I know definitely wasn’t open at the time.
I have needed to use my computer so I haven’t done it yet, but I will kick off a deep scan tonight with automatic setting instead of interactive and see if that works. I am choosing ‘Macintosh HD’ for that and unchecking the 'Mobile Backups' (I don't have a backup disk connected. I only connect it when I do an actual backup about once a month, using time machine).
By the way, for the in depth scan i go through custom scan and chose 'local drive' from the drop down and then check the box for Macintosh HD and uncheck the box for 'mobile backups'. Is that what I should be doing? I have a guest account on the laptop so I want everything scanned, not just stuff on my profile.
Also, ESET has crashed a couple of times when I’ve been trying to open log files (so the icon disappears from the top menu bar altogether.) So I have restarted my computer to get it open again, or just directly opened the app in the applications folder.
I haven’t reproduced the error preventing me saving a MS Word document to a subfolder again, though.
If I do uninstall ESET and fresh install, will it forget all the rules I’ve now allowed for ‘home’ profile and will I have to go through all of that again?
ie put it on interactive until all my apps have had a chance to phone home and be manually ‘allowed’ before putting it onto auto again so that it can complete a scan without interrupting for an approval?
Also, will I need a new key to open or authenticate it or anything?
If I get the chance I will figure out if I can generate a logfile the way you suggest, Peter, if another major problem happens. So far I have downloaded it but I haven’t run it. I’m presuming it will prompt me with what to do because I have no idea otherwise?
Anyway thanks for your help thus far. I am pretty disappointed that this is so difficult for a dunce like me. At least Norton worked and custom settings were understandable, even if it did slow my machine down.
