  • Windows Defender won't turn on.

    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!

    What antivirus do you use? Windows Defender is not necessary if you use AVG, Microsoft Security Essentials, Norton or McAfee. These AV programs have their own antispyware component builtin and allows you to disable Windows Defender by design.

  • 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 It is said that the version of defender is obsolete, but it wont let me update.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.

    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.

  • Windows Defender won't start does not automatically, it's because I use AVG anti-virus software?

    I recently downloaded the free version of AVG v.9, which seems to work very well. However Windows Defender no longer seems work fine, normally this is an error message saying that it does not work and I have to manually start even if I set it to start automatically. Sometimes it does not start at all.  Is it a problem because I use AVG and I have to run Windows defender, while running AVG?


    I got appreciatte all boards.


    Thanks J.

    AVG and defender in the face of a conflict between them.

    And even if you change Microsoft Security Essentials, it will turn off Defender, because it has its own integrated version of Defender.
