It's required to shut down the antivirus during the installation/upgrade of UIM.
Anti-virus software can be turned ON when installation is complete

Before you install CA UIM: Shut down any antivirus software.
Additionally for Linux:
While shutting down SELinux before installing UIM Server is not always necessary, doing so maximizes your chance for a successful installation.
Here are few things to keep in mind related to the anti-virus and Firewall:
1- Ensure the port between the CA UIM system and the database system is open.
2- Specify a starting port during CA UIM installation (the recommended default is port 48000).
3- Ensure that an adequate range of ports are open (for example, ports 48000 through 48020). At a minimum, the first three ports assigned (controller, spooler, and hub) must be open. The port that is used for the distsrv probe communication is dynamically assigned.
