We do NOT recommend installing CSAV for Exchange on the same computer

between the two scanners that are trying to access the same file. This
condition results in an incorrect warning message that will display
repeatedly and cause slowdowns.
This is a temporary condition and will be fixed in a future commercial
release. Again, the products can coexist on the same network but NOT on
the same computer.
* Before you install CSAV for Exchange Version 2.41, you MUST uninstall

- Log on as a service
- Log on locally
- Replace a process level token
- Restore files and directories
* CSAV for Exchange no longer contains the option to send an e-mail
notification to the Sender and Recipient of an infected attachment. Now,
only the mail administrator designated at the time of the CSAV for Exchange
installation receives an e-mail notification that an infected attachment has
been found.
If the infected attachment is QUARANTINED or DELETED, the Recipient's infected
attachment is replaced with a file called VIRUSINFO.TXT. This file specifies the
