Salve,
all'avvio del sistema operativo in automatico si apre mozilla con questo link - http://click.vnn.bz/?checknow=ok&url=C:\Programmi\File%20comuni\Scansoft%20Shared\SSBkgdUpdate\SSBkgdupdate.exe

Come faccio ad eliminarlo ed a non farlo + apparire?

ciao Grazie!!!

ciao a me sa tanto d'infezione,hai provato a far girare il tuo antivirus e magari un antispy?
