When installing McAfee Security protection will Windows Security Essentials block installation?  McAfee tellls me that two security programs conflict with each other.  Can I just turn off Security essentials and allow a McAfee  program thru the firewall to install it? McAfee recommends uninstalling Windows Security Essentials. Is there a way to install McAfee  Protection and keep Windows Security Essentials?  Using  Windows Vista Operating system.  Anybody have any experience at this?   Thank You.
