Warning:
This extension failed to redirect a network request to chrome-extension://gomekmidlodglbbmalcneegieacbdmki/common/mocks/gpt.js because another extension (HTTPS Everywhere) redirected it to https://www.googletagservices.com/tag/js/gpt.js.

Given the error, I would suggest that you disable or remove HTTPS Everywhere - and see if that resolves the problem - as that appears to be redirecting a local call to https.

This isn’t an avast issue but one for HTTPS Everywhere. Not to mention you are running an old version of AIS. The latest version is 2015 10.4.2233.
