Hi,
Would you mind trying the suggestions mentioned in this thread: https://forum.avast.com/index.php?topic=290900
not suggest fully your given topic.my topic is that i turn of web shield.then avast is running perfectly.then after 5-6 minute over,Avast will off automatically.i turned on from Accessibility,again avast work perfectly after sometime avast would off automatically.main topic is that avast is not running in backround for 24 hours :‘( :’( 
Hi,
This generally means that something on your device (either the system itself or another app) is preventing Avast from running in the background. Please have a look for some type of power-saving mode on your device and turn it off.
thanks…automatically avast running now…webshild is running but is not detecting any malwar site in MICROSOFT EDGE.
