To get the best performance from Symantec Endpoint Protection, you must remove any Symantec or other antivirus or firewall product before installing your agents. These programs intercept risky communications with your computers. The programming mechanisms intercepting these risky communications might interfere with the proper functioning of your Cloud Endpoint Protection Agents. To ensure that these products are removed from your endpoints, the installation program blocks the agent install until those applications are removed.
The installation program automatically removes other Symantec and Norton AntiVirus or firewall products as well as tested, antivirus, or firewall product removal tools. The identified applications appear on an Incompatible Applications page where you are prompted to remove them. With user authorization, the installation program launches that product's own Windows Add/Remove Programs tool.
The automatic removal of an incompatible application manages that program's removal tool. If you encounter difficulty with the uninstall of that application, please contact customer support group for that product.
Whenever the installation program encounters an antivirus or a firewall application with an untested Windows Add/Remove Programs tool, the program is identified as incompatible. You must intervene to remove these applications. The installation program's automatic removal tool and incompatible program identification feature is only available in attended or full UI mode.
Once the automatic uninstall operation is finished, the endpoint computer restarts and the agent installation continues. If you manually uninstalled the incompatible product, you must manually restart the Cloud Endpoint Protection Agent install program.
Please uninstall any antivirus program or firewall program from your computer before installing Endpoint Protection. Uninstalling such programs is important even if the install program fails to detect the program or identifies it as incompatible. Running multiple antivirus or firewall programs simultaneously is inherently dangerous; the potential for interference between the applications is too risky to ignore. We encourage you to report these cases to Symantec.cloud clicking the Support link in the Management Console banner.
In larger environments, you may prefer to use your customary techniques to uninstall software from your endpoints. If you perform these operations using Microsoft Active Directory, ensure that the application you remove is also removed from the policy governing these endpoints. This precaution prevents the reinstallation of an application based on your Active Directory policy.
When endpoints run less common antivirus or firewall products, or unrecognized versions of a product, install program may not detect the potentially conflicting product. Potentially incompatible products must always be removed for best results with Symantec Endpoint Protection.
