I have been having the same annoyance with the application opening on startup as the OP and many others who have posted, and was hoping for the version update to fix it. I checked today - after seeing the unwanted screen at startup - and saw a 'Release Name' of "16.0 R6" (presumably = 16.0.6). This update appears not to have fixed the problem!
That is what I was saying. However, it is conceivable that the upgrade happened between when I started up the computer and when I checked the version. I didn't see the problem on startup this morning, so I am keeping my fingers crossed!
Things never run smoothly for me! Got an update today to 16.0 R7 - the good news is I don't get the McAfee screen on booting any more, the bad new is I DO get a nag screen from Windows telling me my windows firewall is off! My first thought was to tell windows notifications to ignore it, but I can't as its blocked because "McAfee has control" Anyone know of a fix?
