    windows defender & security center services keep turning off


    Are you running any other AV or did you have one running in the past? If you didn't use an uninstaller for the AV, then the remnants of it could be causing the problem. Normally any time you install an AV it disables Defender by default.

    If you are getting any error codes please list those, that will be helpful in helping you.

    As torre suggested, might be a good idea to do a reset or even a reinstall.

    It is possible that the Control folder access is enabled that is why its blocking the access to user folders when scanning with HP Solution Center. To resolve your issue, we suggest that you follow the steps in this

    windows security center disabled????????

    i just installed windows defender on my computer (freshly formated new hard drive about 2 weeks ago) and it would not update because the security center was not running. so i went to msconfig and it was not in the services list so i went to services.msc and it was disabled. so i changed it to automatic and started it. after rebooting it was still running, so i restarted it again and it was disabled again, so i renabled it again. and when i went to the security center in control pannel it looked like this
