I am a bit of a novice and as such I don't feel I have the knowledge to help you. Just posting here to share my experiences with Avast! (free suite) to say that I got a fair amount of false-positives and even got blocked out of my own profile page on another site on a number of occasions. I tried playing around with the settings, hardened mode etc, but to no avail.
Recently switched back to Windows Defender (in Win10) and use in conjunction with Malwarebytes Anti-Exploit and Zemana Anti-Logger. No false-pozzies any more, all good! I feel I have a pretty good combo going on here, although time will tell, I guess! All seems very light on CPU usage as well....so far so good!
Best of luck with sorting the issues you are having.

Im a rookie and purely recreational pc user. Im utterly obsessed with security (even though I consider myself a safe and law-abiding internet user!) and run a combo of the following freeware security suites.....
Regular scans with Malwarebytes, AdwCleaner, JRT, HitmanPro
