Windows Defender turns itself off

Windows defender im says that is enabled by default, when I got my computer, it has been transformed, when I turn the Defender, after a random time I find her turned himself back

just to update you, the Defender has been disabled again, not sure when it happened, or how or why! so I think that the problem is always with AVG

Thanks for the comments. Yes, that's AVG 9. If you leave either Defender remain disabled or use something other than AVG 9. Just a note that Microsoft Security Essentals will also disable Defender.

    MSE is an anti-virus, anti-spam and Anti-Malware program all in one. It's light and very user-friendly Windows. It also contains the same functionality of Windows Defender, making it unnecessary and it won't work because it is not needed.

  • If I have my laptop, is why Windows Defender turned off because of group policy?... What is group policy?

    At the heart of the problem is this business of permissions.  Why solo owners of laptops not affiliated with companies or other computers must be prey to group policy and permissions at every turn.  I tried to turn off the UAC and I couldn't find even a file for group policy, and again I am forbidden to use Windows Defender because of this error message.  Only recently have I won control of most of my files and folders by disabling UAC and passing by claiming ownership of my own software and files.  I guess I really two questions: (1) how can I get rid of this feature to administer unnecessary and, as in the good old days, before Vista came, just use my computer without messages such as "you don't have permission to use this...» "and (2) my second question which dovetailed in the the first is" why the hell did I this stupid message from group policy?  There is no groups affiliated with my Compaq Presario, and in fact, it is not a group on my system folder in the first Subscriber.  I'm not very impressed with Vista or Windows Defender.  I could even ignore these problems, but there is a principle here.  I've read enough Articles to understand that I'm not the only person facing this nonsense!

    You cannot change how permissions work under Vista.  The administrator has certain rights and access; However, even for administrators, several parts of the system do not have access (because they are points of junction to towards the rear compatabiility and must not be changed or your programs do not work or because they are system files, you do not make changes.)  Despite this, some of these areas can still be accessed at your own risk - you may do something that can repair only a clean install), I provided the following information about permissions and ownership (which can help you navigate the system correctly and without causing any damage).

    To view your permissions, right-click on the file/folder, click Properties, and check the Security tab.  Check the permissions you have by clicking on your user name (or group of users).  Here are the types of permissions, you may have: http://windows.microsoft.com/en-US/windows-vista/What-are-permissions.  You must be an administrator or owner to change the permissions (and sometimes, being an administrator or even an owner is not sufficient - there are ways to block access (even if a smart administrator knows these ways and can move them - but usually should not because they did not have access, usually for a very good reason).)  Here's how to change the permissions of folder under Vista: http://www.online-tech-tips.com/windows-vista/set-file-folder-permissions-vista/.  To add take and the issuance of right of permissions and ownership in the right click menu (which will make it faster to get once it is configured), see the following article: http://www.mydigitallife.info/2009/05/21/take-and-grant-full-control-permissions-and-ownership-in-windows-7-or-vista-right-click-menu/.

    To resolve this problem with folders, appropriating the files or the drive (as an administrator) and give you all the rights.  Right-click on the folder/drive, click Properties, click the Security tab and click on advanced and then click the owner tab.  Click on edit, and then click the name of the person you want to give to the property (you may need to add if it is not there--or maybe yourself). If you want that it applies to subfolders and files in this folder/drive, then check the box to replace the owner of subcontainers and objects, and click OK.  Back and now there is a new owner for files and folders/player who can change the required permissions.  Here is more information on the ownership of a file or a folder: http://www.vistax64.com/tutorials/67717-take-ownership-file.html.  To add take ownership in the menu of the right click (which will make it faster to get once it is configured), see the following article: http://www.howtogeek.com/howto/windows-vista/add-take-ownership-to-explorer-right-click-menu-in-vista/.

    =======================================================================================================================

    Regarding Windows Defender the most likely reason it is disabled because you have installed an AV or security suite program that does so automatically during its installation (and it was probably necessary for the new software works correctly without causing any problem).  What AV or Security Suite program do you use?

    Regarding group policy, if you wanted to access it go to start / search box and type gpedit.msc and enter and then double-click on the program that appears in the search results.  These AV programs and security can use Group Policy to disable Windows Defender (I don't know how they do it), but it may be there somewhere).  Because re-activate NOT Windows Defender while the other this software is still installed on your system that could cause some conflixts, freezes, crrashes, corrupt and data files and all kinds other problems - it has been disabled for some reason.

    If you want to use Windows Defender, then choose a program or AV security suite which does not disable the Defender during the installation.

    =======================================================================================================================

    I hope this helps.

  • Mac Pro randomly turns itself off (again)

    Mac Pro randomly turns off by itself

    I have never got rid of the problem. Even after having replaced my card stock (radeon 5770) display with Asus Strix GTX 980 Ti, used a Corsair CX750 only power supply to power it. Look like anything, it's over heating, im stimulate fans PCI, exhaust and intake to 2500, 2000 and 2000 RPM (respectively). his strong!

    I'm tired of dealing with this old-tech, unreliable, expensive, overrated,... flat of the weight of the aluminum foil, so please find me a real solution/fix! I could easily put together a very decent PC that 'JUST WORKS' from what ive already spent trying to fix it.

    whenever he stops, I hear a click from the PSU (similar to the clicking sound when you press the power button on the front, commissioning). Trying next turn to the after he died, sometimes the power button will not turn on right away. I had to wait at least 10-15 sec to make it work. When it works sometimes stop with click 2 to 5 seconds after pressing the power button. He sometimes dies right after the chime. It starts also through without any problem.

    A few times when sometimes I watch the LED at the front of the Board (opposite the PCI fan) when he died, I see the two top LEDS blink once I hear that click, those who are highlighted red in the picture (not a picture of my Mac real). It also sometimes flashes when I press the button boot but used to power upward after that he died. Please, what that means?

    The laptop may close due to power cut or overheating...
    Books supports a thermal protection that would prevent other parts of damage in case the internal temperature would rise to a critical level...

    Would it be possible that the cooling fan does not quickly using battery operation?
    I think this should be checked and method in power windows cooling options should be changed.

    4. some people put me to BIOS update.
    Why the BIOS updated? The BIOS update should be performed only if the laptop does not work correctly... but the problem mentioned does not resemble the BIOS update would fix...

  • Re: P305D-S8900 keeps turning itself off

    OK, let's go General information.

    Sometimes, the computer will be shutdown without any reason. It is usually during a virus scan. I installed and uninstalled almost everything out there. No anti-virus program made a complete analysis. They make quick scans very well. I paid $100 nortons to check it out, and they said that there are no viruses on the laptop.

    It doesn't seem to be running hotter than normal... but why would this cause alone stop during a virus scan... and intermittent times during the analysis.

    Sometimes, when he died, I have to wait a while to restart. If I do a recovery, sometimes it stops immediately before that recovery does nothing... sometimes its fine. Sometimes he tries to 1 minute to boot and it stops. It drives me crazy.

    How can I get this figured out... anyone with similar problems?

    I am running Windows 7 Pro 64-bit on the laptop.

    Hello

    If the touchpad doesn't work, you need to reinstall the driver. Please visit the site of the new updates. In addition, if your laptop turns off without reason it could be an overheating problem. In this case, you must give the unit for service partner. If the valid mandate still use it.

    On the other side, it could be a problem of burning software. Well try you to deactivate the option automatically reboot in startup and recovery.
    That you can find in the System-> Advanced-> startup and recovery

    You can also retrieve you wit the OS recovery CD.
