I'm a novice computer user, and I'm currently running a trial of NOD32. I was impressed by all of the comments I read in bulletin boards about how lean and efficient the NOD32 code is. My computer already has too much bloatware; I like the idea of using something that uses few resources. At the same time, I'm getting frustrated with NOD32. Since installing NOD32, when I open Outlook, I frequently get the message: The data file "Personal Folders" was not closed properly... as Outlook checks my PST file for errors. So far I haven't been told of any errors, but consistently seeing this error gives me serious concerns about what NOD32 is doing. Frankly, the integrity of my Outlook data file is more important to me than my choice of which (good) antivirus program to use. Also, NOD seems to prevent my Outlook backup add-in from automatically backing up my PST file. I can execute the backup command manually, but that defeats the point of using the add-in and raises the possibility that I'll forget. Again, something I'm not willing to sacrifice just to use NOD32 Does anyone know whether these issues can be resolved, or should I just try another antivirus program?
