Method 1:
Clean old log files under:
D:\Program Files\Exchsrvr\MDBDATA

Clean BadMails under following path every week:
del /Q /S "D:\Program Files\Exchsrvr\Mailroot\vsi 1\BadMail"


Method 2:
The virus definitions may be missing or corrupt, so we copy the good virus definitions from another machine and overwrite it to the machine that has problem:
C:\Program Files\Common Files\Symantec Shared\*
C:\Program Files\Symantec\SMSMSE\6.0\Server\bm_ruleset*

Note: There is a License Folder under C:\Program Files\Common Files\Symantec Shared . Make sure you do not overwrite the license files. Make a backup before you do these steps.
