As a followup to this issue, I remained ok with no crazy log files bigger than a few kb for 5 days after I shut off the firewall logging. Two days ago, I turned firewall logging back on (see attached), and now I have a log file that is up to 20MB in 2 days. I'm a little suspicious of why this file needs to log so much... what is a reasonable size for it? Is there a way to view what is in the log? It is a bit of a binary file mess.
One of my test PC has McAfee LiveSafe which I haven't re-installed since 11th May 2016. I see the same file in the said location with 80 MB size. Also the FW logging is enabled (since install) which makes me think that we should monitor your PC for a week or two and then decide.
