I am running micrsoft security essentials on a windows 7 64bit system. I also have windows defender and when attempting to turn it on I have three options, turn off, turn on, and out of date. When i hit turn on the out of date pops up and will
not allow the program to turn on. What is causing this conflict. I have tried to download the program and it says it is already installed and won't allow a download. Why can't I turn the darn thing on?
