In NOD's Alert screen which flashes on receipt of an infected email could someone please tell me whether Quarantine and Delete are equally valid separate options? If I choose Delete alone, then the file is gone and mail can continue to be received. Likewise if at the same time I choose Quarantine. But if I just choose Quarantine on its own and exit the screen, then I get the warning "Closing this window without selecting an action may result in infiltration". If I repeat the process and stick with Quarantine I get the same warning twice again, after which it gives up, quarantines the file and on we go. What I'm not clear about is what is meant by "selecting an action" if this doesn't include Quarantine? Hope this not a silly question - I'm new to NOD as an alternative to NAV (where quarantine was always a separate option).
