Windows defender won't turn on or update.

I have a toshiba satellite laptop computer running windows 7 Home premium. I am running Microsoft Security Essentials on my computer. It scans and says I need to download windows defender in offline mode to remove the virus completely. I have the Defender on my system, but it does not start. It is said that the version of defender is obsolete, but it wont let me update. I remove MSE, is there a fix?

MSE automatically stop Windows Defender because he has the same properties. If you have a virus and it does not remove MSE, WD will not.
 
Download the free versions of these tools. First check the updates and then run a full scan with each. It will take a while.
 
 
 
If you still get an error message after it, copy & paste into an answer here.

    I don't know what happened, but my Windows Defender just turn off by itself. I can't activate it. The Windows Security Center always give me the same answer. I'm really frustrated here. Please help me!

    You are running Microsoft Security Essentials, AVG, Norton or McAfee? If you run one of those, she didn't have Defender. It's good, not bad. Not only is there potential conflict, but there is no reason to have both; basically to have something very similar to the built-in Defender, and both running at a time will be your performance level and create the risk of problems that are contrary to the other.

    You cannot uninstall Defender - it is a part of the operating system.

    To install MSE should properly to completely shut down Defender, because it contains an improved version of it. It is therefore likely that something has blocked the operation of MSE, or at least of its Setup program.

    My best guess is that you need to uninstall MSE and then run the removal tools for ANY other antivirus you have EVER had installed on this computer, and then reinstall MSE again. Norton and McAfee are particularly bad for this kind of problem. I also suggest uninstalling MBAM while MSE is being installed - just in case there is a conflict.
