I am using 3.0.551.0 up-to-date. I have scheduled to backup my outlook .pst file evernight to a network storage device. NOD keeps killing it stating this: 2/3/2008 11:05:49 PM Real-time file system protection file probably unknown NewHeur_PE virus unable to clean NT AUTHORITY\SYSTEM Event occurred during an attempt to access the file by the application: C:\WINDOWS\system32\ntbackup.exe. This happens every single night. I have even gone in and added the .exe to the exclusions list. If I manually run it, it works just fine, but the scheduled task gets killed every night. Any ideas?
