googlesyndication pop up
In the past few days I have seen a definitely annoying message popping up on Safari with the script "Do you want to allow downloads on "tpc.googlesyndication.com"? You can change which websites can download files in Websites Preferences.
Obviously I click on "Cancel" and so the download of the file f.txt is blocked.
I don't think it's normal, may it be a virus?
Thanks
