Hi. I'm running Avast on my Windows 10 Dell. Tried to run Smart Scan today, but it gets to 6% and just sticks there.
I have the same Avast on a laptop (Lenovo) also Windows 10 - and it seems to be working on that.
I noted some messages back in November 2015, and a comment that Avast know about the problem and are working on it.
Now May 2016, so any update?
