By default you can remove McAfee Agent using the uninstaller that comes preinstalled with your Windows operating system. However, if the program can't be uninstalled, an automatic removal tool helps force-uninstall the program. If all else fails, removing the program manually deletes installed files and registry entries to delete the program completely.
The Windows uninstaller fails to remove the program if McAfee Agent conflicts with third-party programs, or if issues with an upgrade interfered with the program's files. Uninstall issues are also caused by the "Prevent McAfee services from being stopped option" in VirusScan Enterprise 8.5i and later. If McAfee services aren't stopped, error messages are displayed when you try to uninstall McAfee Agent.
If the Windows uninstaller is incapable of removing McAfee Agent, use Frminst.exe, an uninstaller primarily designed to remove the program automatically. Before removing McAfee Agent, disable McAfee services protection in VirusScan Enterprise. If you're using VirusScan Enterprise 8.5i or later, disable the Access Protection feature or McAfee Agent won't be successfully removed. After disabling the setting, click "Start" and "Run." If you type each of the following commands individually without quotes and press "Enter," the program is uninstalled automatically:
--C:\Program Files\Network Associates\Common Framework\frminst.exe/forceuninstall.
--C:\Program Files\McAfee\Common Framework\frminst.exe/forceuninstall.
Restart your computer for the changes to take effect.
If you're still unable to uninstall McAfee Agent automatically, use manual removal as a last resort. Before removing the program, you must disable the McAfee Framework Service in the registry. To open the registry, type "regedit" mins quotes in the search box on the Start menu, and then press Enter. When you open the registry, the file is located in the following path: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\McAfeeFramework]. Double-click the "Start" value and change the Value data to 4 to disable the service. Restarting your computer allows the changes to take effect. In addition to disabling the registry entries, press "Ctrl-Alt-Delete" to open the Task Manager. Click each of the following processes from the Process tab and click "End Process" to disable them: Mctray.exe, Updaterui.exe and Naprdmgr.exe. The final step to removing McAfee Agent involves deleting the program's registry keys.
Removing McAfee Agent manually is a difficult process that involves modifying the registry. Modifying the registry should be left to someone who has a deep understanding of computer troubleshooting. If you make a mistake, you risk damaging system components, which can lead to serious computer problems. If you don't feel comfortable modifying the registry, it isn't advisable to tamper with it.
