My Acer laptop slower, w/ occ. freezes since 17.1.2286 v Avast Internet Security

Hi! Have an Acer Aspire laptop – Intel(R) Core™ i3-3120M CPU w/ 2.5 GHz 2.5 GHz ; 4 GB RAM : 64-bit ; w/ Windows 10
Yesterday, updated Avast Internet Security to program version 17.1.2286
Since the update, I have noticed a significant slowing of my use of current stable version of Google Chrome, w/ several freezes.
I am not running anything differently in the background–just the usual stuff–Dashlane, Snagit, Task Manager, Super Anti- Spyware. Current scans negative for malware/viruses.
Has anyone on forum experienced this? Any solutions?
Thanks in advance.

Have you tried rebooting the system ?
