We have a similar problem with our web site.
https://www.e-assura.ch/We know that we are as big as Hotmail but a lot of our 100 k customers are having trouble logging in our web site using Internet Explorer and Avast.
Tested Avast last version, updated today, software and definitions. Tested IE8 and IE10.
In fact, it is blocking our JavaScript. It is used to do login in the website and make some "show / hide" fields in the page.
Example: in the login page in french (fr), the link "Mot de passe et/ou nom d'utilisateur perdu?" should hide some fields and show others. Instead, a javascript error alert shows up.
Strangely if after the first page load I do F5, everything works fine again. It is always the first page load that is not working.
When disabling the avast extension in IE, it works fine always.
Tried to add it to Exclusions too, but no luck at all. (When I add it, it doesn't accept with the https?!)
A customer indicated another web site where she had problems too. I tested and saw it in action.
