Unfortunately Avast EasyPass and Avast Online Security cannot be used with the Edge browser
because it does not support the use of plugins. To use plugins you need to configure Windows 10 to use a browser that
allows plugins by default. To change the default browser setting in Windows 10 do the following:
- Go into the settings of your preferred browser and set that browser to be your default.
- Windows opens the Choose default apps screen.
- Scroll down to the Web browser item and click the Edge icon.
- In the Choose app screen select your preferred default browser.
