G-mail is a web based e-mail, and virus scanning is already carried out on the g-mail servers. NOD32 will only scan mail that is being delivered to your local machine directly, through a client such as Outlook or Thunderbird. IMON and AMON will defend you from any infected attachments you download (and that the server scanning has missed), so I wouldnt worry. You are protected.
The problem lies elsewhere. Gmail account doesn't use port 110 (pop3) for downloading the e-mails to the mail client. It uses secured communication on port 995 (SSL) instead. As this communication is encrypted, IMON cannot check it. However, AMON will do the job if there is any infiltration.
It's webmail. Any files you wish to download...AMON would scan..as it's the real time file protection component.
It's webmail base, but you can also use a email client such as Outlook or Thunderbird. It uses port 995 (SSL). This communication is encrypted and IMON can't scan this. AMON (real time) will step in...
