By default Nod32 antivirus (as well as many others) inserts its signature to every message it checks. IMHO it is completely useless waste of traffic, ink and paper (as many companies use to print significant messages). As aI can see, it is very often to see an extra page printed having only a piece of AV signature on it and no useful information.
How to disable this signature without disabling E-mail check? I couldn't find the option in Nod32 4 settings.
