further tab from avast! when starting Firefox

Avast Free Antivirus / Premium Security
1

Hi,

After installing the latest avast! Free antivirus Update, my Firefox always opens a second tab (http://aos.avast.com/upgrade/2006) when I start it.
There’s only one Startpage in my Firefox settings, and I don’t know how to delete the ennoying avast!-tab :frowning:

Would be great to hear from you :slight_smile:
