The problem for us ‘avast users’ in the forum, is we aren’t seeing the problem as we aren’t trying to log in as we aren’t registered/members at your web site. So we physically can’t access the areas that your users are reporting as a problem.

Interestingly when I tried to visit your site I got a WOT notification, http://www.mywot.com/en/scorecard/newlifebobba.fr One of the comments is recent and also relates to JAVA Virus. Whilst WOT isn’t the most reliable reputational database it does seem related. So any images of the alert would be helpful.
