I too have been experiencing problems with Avast, but I'm using the Avast Security Suite, and my computer has been slowed down to a snail since Avast got new updates over the past month or so, even now my HD is being thrashed by Avast and writing this post is even slowed down, I type a line and I don't see it for at least 2 seconds or more. I'm seriously thinking of totally removing Avast and just rely on the software that MS intended Windows 10 to use, and that's Windows defender and the Windows firewall, I have previously tried Norton, Avg, and when I tried Avast about a year a go, it was fine, sitting there doing it's job, and now it's hogging about 80% of the resources.
