when i try to login on mail.com, i get a "werbung" popup. this does not happen in Google Chrome or I.E. or Opera. What could be the issue? I have deleted Firefox, cleaned system and registry and reinstalled but it happens again.

I am asking on behalf of my wife who clicked a link inside an email from a friend that we now know didn't send it. When using Firefox, when clicking in the login section, a popup starts in the top left of the screen that has a title of "Werbung - mozilla firefox" which contains adverts. when trying to close, it asks "do you want to leave this screen" or "stay on this screen"

I have deleted Firefox from the system, cleaned the system, scanned for viruses and malware using Comodo Internet Securtiy. Restarted the system. Logged in using Chrome, I.E, Opera with no problem. Installed Firefox 4 again. Same issue occurs. Help please

I believe that our “Werbung problem” adds an additional second hyperlink to the pop-up window. This second link is activated whenever you trigger a saved hyperlink to a Mail.com site.

I had the same problem and eliminated it by deleting all bookmarks, hyperlinks and automatic links that take firefox to a mail.com address. So I just deleted all bookmarks I had saved for mail.com. I also changed my home page link because it also went to my email at mail.com. I then did a warm boot, opened firefox and re-saved my bookmarks and homepage to the desired addresses. Good luck.
