Symantec 10551441 - AntiVirus Corporate Edition Administrator's Manual page 133

Using the Symantec System Center, you can set exclusions for specific file
extensions and folders. In addition, certain Symantec AntiVirus scans allow
exclusion by named folder (for example, you can exclude scans of the path
C:\Temp\Install). To maintain security, you cannot view or exclude specific files
from the Symantec System Center. You can, however, exclude specific files
using the Symantec AntiVirus client or server user interface. You may want to
exclude files that trigger false positive alerts. For example, if you used another
virus scanning program to clean infected files and the program did not
completely remove the virus code, the file may be harmless but the disabled
virus code might cause Symantec AntiVirus to register a false positive. Check
with Symantec Technical Support if you are not sure if a file is infected.
Table 3-5 describes exclusions.

Setting exclusions
Symantec AntiVirus exclusions behavior is as follows:
When Symantec AntiVirus applies exclusions, the excluded items are not
■
scanned. If the file is not excluded, it is scanned.
For virus sweep, manual, Auto-Protect, and scheduled scans, Symantec
■
AntiVirus takes no action on excluded files.
Enabling and disabling exclusions can improve performance depending on the
situation. For example:
If you copied a large folder that was in the exclusions list and the exclusions
■
setting was enabled, the copying process would not take as long since the
folder's contents would be excluded.
If you copied a large folder that was not in the exclusions list, disabling
■
exclusions would improve performance.
