Rollback refers to reverting to the previous
                  version of the 
Virus Pattern,
                  Smart Scan Agent Pattern, and Virus Scan Engine. If these components
                  do not function properly, roll them back to their previous versions. 
OfficeScan retains the current
                  and the previous versions of the Virus Scan Engine, and the last
                  five versions of the Virus Pattern and Smart Scan Agent Pattern.

               OfficeScan uses different scan
                  engines for clients running
                  32-bit and 64-bit platforms. You need to roll back these scan engines
                  separately. The rollback procedure for all types of scan engines
                  is the same.
