Unlock the Host IPS Client UI, and click on Help, Troubleshooting. Enable the Show product in Add/Remove Program list option. Before uninstalling, you will need to disable the Host IPS module to disable the self-protection signatures. If you don't the uninstall will fail.
Instead of using the Add/Remove Programs, you can use the command line uninstall, which you can get from HKLM\Software\McAfee\HIP\UninstallCMD, however, you still have to disable the Host IPS module first.
The KB article for manual uninstalls should only be used if the "automated" uninstalls fail.
thanks for the right answer.
