any way to repair? can't get to work the protection

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.

Securing Windows 2000/XP/Server 2003 services HOW TO

I will try changing their settings sometime, the one thing I've noticed about this guide is that it doesn't list the Windows services that NEED to be left as local system, so some people might not be too sure what they're doing and worry about any that aren't listed. Just a suggestion that you might want to include in any future revisions. *Smile

The non-default ones I have that you have not listed are:

.Net Runtime Optimization Service v2.0.50727_X86
Ati HotKey Poller
ATI Smart
AVG E-mail Scanner
AVG7 Alert Manager Server
AVG7 Update Service
BlueSoleil Hid Service
Bluetooth Support Service
ewido anti-spyware 4.0 guard
iPod Service
Messenger Sharing USN Journal Reader Service
Service Layer
Windows Defender Service

The problem is that the only ones of these I actually use are The AVG and Windows Defender services and occasionally the "Service Layer" service (related to Nokia PC Suite) and the "Messenger Sharing USN Journal Reader Service" (related to WindowsLive Messenger). Anyway, I'll see how much I can secure those and post back how I get on. I'll try to test it sometime this week just I'm a bit waring of changing the AVG settings because the only way to test if it was still working would be for a virus to be detected... and I' rather I didn't get viruses!

 

Windows Defender Error 1058: can't start service

I've seen posts regarding similar behavior for Windows 7, but not for Windows 10. I've tried a few of the steps but some of them (like specific registry key updates) are not applicable, since the registry seems different than previous versions.

Symptoms

• Windows Defender always fails to start, gives "Error 1058"
• Under Settings > Update & Security > Windows Defender, every option is greyed out
• Can't manually start the "Security Center" service
  • Initially set to "Disabled"
  • Change setting to "Automatic," start service manually
  • After a short time, it reverts back to "Disabled"

Troubleshooting Steps

• Performed virus/malware removal
  • Malwarebytes, SUPERAntiSpyware, HitmanPro, AdwCleaner, Kaspersky's TDSS Removal, Bitdefender, Spybot
  • Individually installed, scanned, and removed each
  • Found some adware/viruses that were removed
  • Nothing shows up in any scans now (seems like everything active was removed)
• Checked Group Policy Editor/registry key for the "Disable Windows Defender" setting
  • Made sure everything was set to "enable" Defender
  • Still see symptoms
• sfc /scannow
  • Showed some errors that couldn't be resolved
  • Seems to be missing critical files in the running and backup file list
  • I have the CBS.log that was ran immediately before posting; not sure how to attach it or if I should include a snippet
  • EDIT: just re-looked through the log output, seems like most of the "check failed" errors were for different shortcut files (Task Scheduler, etc.). Not sure how applicable this is now

Possible Solutions

• Download + reinstall Windows Defender to replace missing files
  • Not sure if this is even possible, given that it's a core system component in W10
• Restore Registry keys back to default settings
  • Virus seems to have messed up several places
  • Nothing specific to Windows 10 online for getting Windows Defender back to stock in registry
