Windows 10: Does "MS Defender" work?

Dear Sir/Madam:


Since I bought this PC w10, I use the build-in "MS Defender" for "AV"


Today I check the"Defender":

C:/Program File/Winders Defender/Offline/OfflineScannerShell.exe

It says:

OfflineScannerShell. exe System Error: Can not find mpclient.dll

Reinstall it please.


What should I do? -- Zhao

MS Defender Won't Load After Upgrade to Windows 10 Ver 1511

Problems starting Windows Defender in Windows 8/8.1/10

Nothing worked, HOWEVER, the last step is to Delete Conflicting Registry Entries. My registry contains one of the entries listed (MsMpEng.exe) however, REGEDIT could not delete this entry as I was directed.

Problem still exists; as soon as I start MS Defender, it stops.

Any further suggestions?

Windows Defender Not Working in Windows 10

Hi,

Thank you for using Windows 10.

Sorry for the delayed reply. I suggest you to Set Windows Defender to Automatic - You can set the Windows Defender service to Automatic, Disabled or Manual. Setting it to automatic might solve the problem. Follow these
steps:

• Click Start > type services in the Search box > click Services in the Programs list.
• Search for Windows defender.
• Double-click Windows Defender, and click Automatic in the start-up box > click OK.

Also, follow the below mentioned steps and check:

• Open the Task manager. Here’s a tip: Press CTRL+Shift+ESC.
• Click File > Run New Task
• Make sure you have a check mark beside “Create this task with administrative privileges”
  
• Type CMD
• Type the following 2 commands at the CMD prompt:
  
  dism /online /cleanup-image /restorehealth
  
  sfc /scannow
  
  
• Close the CMD window

Keep us posted on the status of the issue and we’ll be glad to help.
