Beta 3 is still working really well for me under Windows 10. Apart from the network scanning bug which was fixed, I've had no other problems. I experienced a slowdown caused by Avast only once in the last two weeks (and I use my laptop for many hours a day, every day). The rest of the time, unless I'm running a scan, I never notice any slowdowns caused by Avast.
However, I no doubt will uninstall it soon, due to issue I've previously mentioned, where there is no option to add a detected file to the ignore list. I guess for most people, this will be no big deal. But, for me it's a huge issue. It's a shame, as apart from this, in my opinion Avast is brilliant.
