Try our new Avast version which includes new version of SZBrowser: https://forum.avast.com/?topic=196445.0
Solved?
New update seems to have solved the issue now thanks
When I sent a ticket they will not provide support unless you have the paid version. So if the video downloader does not work (even reinstalled), basically they’re saying too bad. I wouldn’t make a purchase if they will not provide an answer for the free version.
