My guess is that it has to do with the scan on "read" emails. It is intermittent and users get a blank email or an email missing a large portion. Tonight, I got an email and in the little outlook preview window that pops up in the taskbar (by the clock), the mail read fine, but when I switched to Outlook to read it, the mail was almost blank. It's like NOD32 is glitching and stripping out part of the message, or all of it entirely. Platform is XP Pro SP2 and Outlook 2003. SMTP/POP3.
