How to Fix: Malware and Spyware Protection Malfunction. Please restart.

Neo14000 W/ Member Posts: 8 Security Scout

For some time now, I've been getting an alert on my Policy Manager console, with this message: "Malware and Spyware Protection Malfunction. Please restart." I've checked the machine remotely and it seems that Windows Defender is still activated, but as soon as I deactivate it, it reactivates after restart. Do you know a way to deactivate it permanently, or could the problem be coming from somewhere else?


Have a nice day!

    Hi @Neo14000

    Thank you for contacting WithSecure Community and sorry to hear that you are getting Malware Protection malfunction error.

    On the affected host, can you please check if Ultralight Core has been installed ?
