Windows 10: How should I really treat a windows defender warning?

Usually windows defender doesn´t appear to do shit so I use Kaspersky Total Security anyways to check for viruses. Just for fun I wanted to test Bixby Studio which should be clean anyways and is confirmed by Kaspersky yet Windows Defender complains about the attempted execution of an unknown Software.

Is Windows Defender actually doing some Antivirus stuff or just complaining about a missing signature or something like that?

Installing Apps on Windows 10 Has Windows Defender Finding Malware

Thanks for the reply,

I already know how to do that, so I guess I should have included that. Doing that for each app would be a little bit of a hassle. Admittedly, I really do not use many apps unless they pique my interest. Anyhow, these same apps didn't incur the same warning
from Windows Defender in Windows 8.1 when Pokki was installed by default. It just seems odd now it does this with Windows 10.

 

Windows Defender Battery Life Warning - infinite timeout

After the 1703 Creators Update installed, I received a battery power warning that "The sleep timeout on this device is currently set to infinite". Opening the power settings and correcting the battery timeout from 'Never' to 15 minutes did not clear the
warning, even after a restart. I then changed the plugged in setting from Never to 5 hours and restarted but the warning still persists.

UPDATE

I tried the solution suggested below and assumed this had no effect because SFC did not find any problems and the flag remained. Following the steps for the clean boot includes disabling Defender warnings so I could not see if there was a warning. After
the failure of the DISC process and a further reboot, I used Task Manager to re-enable Defender warnings. The warning is no longer reported. It may be that simply using the start-up tab in Task Manager to disable warnings followed by a reboot and re-enabling
warnings is all that is required. I tried to test this by setting the timeouts back to 'Never', but Defender no longer warns that I have an infinite timeout set...

 

Windows Defender problem

Hi Ernst,

To troubleshoot this issue, we suggest that you check the Windows Defender service if it's running. If you are using a third party spyware/malware program, it may disable the Windows Defender service. To do this, please follow the steps below:

• Press Windows + R key.
• Type services.msc.
• Right-click Windows Defender service and click
  Start.

Let us know the result.
