Yahoo Mail: There appears to be a problem loading the message list

Unable to access yahoo mail after initial page load. I have read in various post Avast is causing the issue with other sites too. Can you guys fix it? Else i will uninstall and try other solutions.

Installing Avast! Free Antivirus 11.1.2245 from here http://www.filehippo.com/download_avast_antivirus/history

and then restarting windows machine, this issue starts to happen in chrome → net::err_spdy_protocol_error

windows 10 / Chrome 48.0.2564.103

Update to the latest version (2016.11.1.2253): https://forum.avast.com/index.php?topic=182468
