IWSVA provides an automatic rollback feature that you can use to restore a previous
virus pattern file in case something goes wrong during a virus pattern update. By
default, IWSVA is set to keep an archive of three previous virus and spyware pattern
files.
To check or change the number of virus pattern files to archive:
-
In the main IWSVA menu, click Updates > Connection Settings.
-
At the bottom of the screen, type the number of virus pattern files you want to keep.
-
Click Save to update the IWSVA configuration file.
