sudo /usr/local/McAfee/AntiMalware/VSControl stopoas
sudo defaults write /Library/Preferences/com.mcafee.ssm.antimalware.plist OAS_Enable -bool False
sudo /usr/local/McAfee/AntiMalware/VSControl stop
sudo /usr/local/McAfee/AntiMalware/VSControl reload
Or completely uninstall:
sudo -s
cd /usr/local/McAfee/
./uninstall EPM
One more thing that can be done is to turn off the KeepAlive in the plist of all mcafee files in /Library/LaunchDaemons. Once you restart you machine then you can just kill all the processes. This is useful because you can use a script on startup to disable them and if you Corporate IT notices you just restart without running the script and the system is back to normal running this piece of 5!-!!t software.
