There may be occasion to revert, or rollback, IWSVA to a previous version the virus pattern file. The two most common reasons for a rollback are:
false positive—a harmless file (or group of files) is incorrectly detected as unwanted
corrupted files—transmission of the pattern introduced an error
Rollbacks are only supported for the virus pattern file, and only for registered versions of IWSVA.
From the main IWSVA menu, click Summary.
Select the component you want to rollback from the list that appears.
Click the Rollback button.
Click your browser's Refresh button to see the results of the rollback in the Current Version and Last Update columns.
Note: To perform a rollback, IWSVA must have at least one previous version of the file on hand. You can set the number of Virus and Spyware pattern files to archive in Updates > Connection Settings, at the bottom of the page.
