Windows Defender quarantined Slicer.exe

Support
1

On my university-managed computer, Slicer.exe disappeared from the install tree. Windows Defender quarantined the executable due to “potentially unwanted behavior”.

It states that it detected Program:Win32/Beareuws.A!ml, which must be a false positive. I’ve submitted the executable to VirusTotal and nothing was detected (just one bogus engine out of 68 indicated “unsafe” without any more information).

@jcfr You have submitted false positives to Microsoft before. Would you be able to submit this Slicer5 Slicer.exe executable?

I will engage with our security team and follow up.

For me it was the with the latest definition version as of 2022-05-25. I’m not sure if it’s still removes the executable. I’ve tried a manual scan of the Slicer folder and it did not do anything, but maybe because I’ve manually restored the file before.
