Defender AntiVirus

There are 4 options under Defender. Two refer to AntiVirus; AntiVirus Network Inspection Service & AntiVirus Services. Under Startup Type these two are listed as manual and the Status column said Inspection Service is running. When I clicked on the Start
button in Properties, I got an immediate message: "Win.. Def.. Anti.. Serv.. on local comp.. started and then stopped. Some services stop automatically if they are not in use by other services or programs."

 

Unable to Re-Start Windows Defender Services

A little background first, I downloaded a file and started to install it when Defender caught the virus, but didn't contain it. So I downloaded Malwarebytes to scan and remove the virus.

After I loaded Malwarebytes I noticed I wasn't getting anymore Windows Defender definitions but I noticed the Windows Defender services were stopped and I figured Malwarebytes stopped it and that was the reason I wasn't getting anymore updates on Defender.

I uninstalled Malwarebytes but now I can't restart Windows Defender.

If I got to Control Panel then Security and Maintenance window. Both buttons to turn on Defender are grayed out.





If I search for Windows Defender in the search window on the task bar. This is the result I get.





And lastly, if I go into Task Manager Services, there are 2 entries for Windows Defender, both are stopped. If I try to restart them this is the message I get.





So is there anything I can do to restart the app or does it require more drastic steps such as reload 9926?

 

Windows Defender disabled and is unable to start


OK. I am not sure if you can complete the steps below.......................
In the search box, type services.msc > Enter
Items in the Services box are listed alphabetically.
Scroll down to Windows Defender Service...........................
at Status heading, it should be.................................... Running
at Startup type, it should be......................................... Automatic







If that is not what yours said, right click at Windows Defender Service > click Properties >
can you change the Startup type to Automatic and Service status to Start ?
If yes, do so and click OK when done.
