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.

Security Centre reports Kaspersky and Windows Defender turned off


In Windows Settings / Update and Security it only has Windows Defender in the list on the left hand side, this reports "The settings for Windows Defender Antivirus aren't available because it is turned off"; then gives the option to Turn on Windows Defender Antivirus.

In old-style Control Panel / Security and Maintenance, under the Security heading, it reports Windows Defender Antivirus and Kaspersky Internet Security are both turned off, and gives a button View Antivirus Applications. This shows the dialogue box I mentioned in the OP which lists the two installed virus protection applications: Kaspersky Internet Security - Off, Windows Defender Antivirus - Snoozed.

Kaspersky reports Your Computer is protected and can be seen in Task Manager to be running and consuming resources.

As Windows - falsely - claims neither is running there's no option to turn one off.

I'm wondering whether it started with this week's Windows updates.

I might try uninstalling and re-installing KIS to see if it makes any difference.
