(Sorry if this has been addressed already, but the search function doesn't like keywords less than 4 characters ) Still going through my initial "learn and get comfortable with it" period, so I have yet another question about NOD32 v4: Using the context menu, I scanned my 315mb Outlook pst, and was surprised that NOD32 finished instantly ("0 seconds" per the stats), telling me there were no infections found. Was it really scanning the file? I notice that the pst file does *not* show up in the full-system scan logs as a non-scannable file, yet I can't imagine it can actually scan in 0 seconds. If the answer is that NOD32 *doesn't* scan the pst, my questions are (1) Should this matter, if I have already used the Outlook-integrated NOD32 interface to scan the the Inbox and all other folders in OL -- as well as any new incoming mail? (2) Why wouldn't inability to scan a pst file show up as an exception in a full-system-scan log, similar to other non-scannable files and archives? Thanks.
