My Windows 7 wallpapers were not working so i used system restore.
But evern since i used symstem restore my McAfee real time will not switch on.
Please follow the below steps and let me know if the real time scanner stays turned on .
Check and delete if you have any other security software in the computer.
Run this tool from here and restart the computer.
Open Mcafee and check for updates..
Let me know if still th real time scanner gets disabled.
