...a verbal shoving match. nobody answered the question.
IF IT WORKED AS EXPECTED - IT DIDN'T WORK FOR ME. The answer, for users of AVAST INTERNET SECURITY 2015 is this...
1) open AVAST USER INTERFACE (right click the avast icon in the system tray)
2) click SETTINGS - gear icon at the bottom of the left side
3) click on ACTIVE PROTECTION at the top of the right pane
4) click on 'Customize' beside WEB SHIELD
5) click on 'Exclusions' -- 3rd from the top of the left page
6) CHECK the box beside URLS TO EXCLUDE
7) enter the url of the site you want to EXCLUDE and click ADD
...you can find your way home from there.
good luck
