Just to remember.
Regardless of the method you use to run the installation program, the program checks for and uninstalls the following antimalware clients:
- Symantec Endpoint Protection version 11
- Symantec Corporate Edition version 10
- McAfee VirusScan Enterprise version 8.5 and version 8.7
- Trend Micro OfficeScan version 8.0 and version 10.0
- Forefront Client Security version 1 including the Operations Manager agent
What about Tamper protection?
But 1 important note about tamper protection. (password protected uninstall)
If the previously installed antimalware client has a tamper protection feature enabled, for example, if the software is password protected, you need to disable that tamper protection before you can install Forefront Endpoint Protection. Otherwise, the Forefront Endpoint Protection installation program will not be able to uninstall the existing antimalware client.
What about auto anti-malware remediation?
In addition, if you use a mechanism to automatically distribute and install antimalware to your client computers, you need to disable automatic installation before you install Forefront Endpoint Protection. For example, if you use WSUS to distribute Forefront Client Security (FCS) to your endpoints, before you install Forefront Endpoint Protection, you need to configure WSUS to not automatically reinstall FCS.
