Try clearing your browser cache/history and cookies, restart the browser and see if that resolves it.
Even if you have an ad blocker I use uBlock Origin and uMatrix (not strictly an ad-blocker), avast would still be checking.
If you aren’t directly trying to connect to that domain then the Avast Online Security (browser extension), isn’t the problem unless it is a false positive.
However even then it should be the Web Shield doing the blocking (not sure if that is what it is), it should throw up an Avast Alert window.
See attached Web Shield alert with details selected - I don’t use the Avast browser extension.
