Hello

If you use Norton, AVG, Avira, Microsoft Security Essentials, McAfee, etc. the default action is for Windows Defender must be disabled, that these AntiVirus programs have their own Antispyware Applications.

There is nothing to worry.

Using both programs at the same time can cause system conflicts, etc.

If you are using one of the above AntiVirus programs, this Information from David O - Support Engineer shows you how to manually enable Windows Defender (disregard information from uninstalling; not possible in Vista):

"Go to start, Control Panel, Administrative Tools, Services. Look for Windows Defender.

Right click and select Properties , ensure that Startup Type is automatic.

Once modified, click apply and OK.

Quit and restart your computer. Check the back take the same path to confirm that Windows Defender has started"

If you want to have additional protection against malware using the version FREE of Malwarebytes AntiMalware:

    Hello

    What is display / causing the error message? Some security/antivirus/antispyware products can cause this
    error. On those which do you use, including everything that you have ever even those uninstalled (remainders
    may cause problems). AVG and others have been known to disable Windows Defender.

    Start - type in the search box - Services - find top - Right Click - Run as Admin

    Windows Defender - value STARTED and AUTOMATIC

    or set MANUAL and STOPPED if necessary

  • Backup of Windows 7 - the system cannot find the specified path, error Code 0 x 80070003

    I have serious problems back up my own machine to a share on our FILE SERVER as \\FILE-SERVER\Backup\

    I have already backed up another PC using exactly the same settings I used on my PC successfully.  So I guess it's nothing to do with the FILE SERVER or the backup settings.  There must be something to do with what I'm trying to backup of my machine.

    First, some background.  This exercise was started when Windows Server 2008 r2 o/s fell one of our servers.  I tried to reinstall the operating system several times, without success.  In the end, I caught another drive and rebuilt the o/s on the server.  Then I got in trouble by promoting to a domain on the network controller.  In the end, I've renamed server FILE Server for FILE SERVERS.

    We share regularly four records on what is now the FILE SERVER:

    \\FILE-SERVER\Backup - a folder where the backups of all other devices are written, so that they will be saved with the server

    \\FILE-SERVER\Company - contains all of the data of our company

    \\FILE-SERVER\GEM - this is for our own database application

    \\FILE-SERVER\Install - contains all the installation files for the software we use

    These are all inmates on a RAID 1 array that is separate from the system drive that covered.

    On my laptop, I had made these "Available offline" shared folders, while I still had everything that is available to me when I was away from the office.  They were of course shared under \\FILESERVER\... not \\FILE-SERVER\... Before the server down, I had backup works fine on my machine.

    After having got the server up and going again, I started going there from the WIndows 7 Client PC backups again.  I started with a desktop computer, which of course have not all offline files.  This turned out to be relatively simple.

    Then, I started with my machine.  Initially I did not 'Available offline' folders shared meanings.  I created my backup using exactly the same settings that had worked OK on the desktop.  But when I ran the backup I got:

    The system cannot find the specified path, error Code 0 x 80070003

    I tried all sorts of things to make it work:

    • with or without an image of the system.
    • reducing the backup in a single folder.
    • do it again 'available offline files

    Nothing makes no difference.  In the end, I looked in the Sync Center to look at the offline files folder.  Under mapped network drives I discovered that I still had the files and folders in \\FILESERVER.  In their Menu Popup 'Always available offline' is grayed out.  So I deleted the Copies offline.  This delete the files in the folders but not files.

    Since I could find no way to delete the old mapped network drives.  I decided that I had painted myself into a corner.  So I bit the bullet and re-installed my laptop too.  This will get rid of the unwanted old mapped network drives - BUT NOT the ERROR!

    HELP - I'm running out of ideas!

    I have a WORD Document that all the settings that I used on the server and Clients, as well as the reasoning behind these settings, documents, but I can't find a way to download.

    Hi Brian,.

    These problems occur because the folders or libraries that you are trying to back up or restore include a reparse point.
    Analytical points are similar to shortcuts Windows or Unix symbolic links. A point of analysis can be used to point to a file that is moved temporarily to a different drive. For example, a reparse point would a folder such as C:\DVD to point to drive E, the real DVD player.

    Perform the steps from the link below and see if the backup works.

    Follow the advice of microsoft at the link below

    This problem occurs when Windows Setup encounters an error. Error code 0 x 80070646 and error code 646 are generated by Windows Installer. These generic errors indicate that Windows Installer has encountered a problem. When you encounter errors that are described in the section "Symptoms", the problem may be caused by an incorrect value in the registry.
