Which builds are installed from Kaspersky products?
Which backup program?
Did the backup failed if service from KAV is stopped?
Builds Being Used
kav5.5 1388 For Exchange Servers
kav6.0.4.1212 Anti-virus For Windows Servers
I am using SBS 2003 R2 Default Backup Application.
Backup will work if KAV is stopped
