Windows Defender claims Wacatac.C!ml trojan in Grub2Win.zip

[Karsten Hahn]

Hello,

Windows Defender again claims Grub2Win.zip is infected with the a trojan named "Wacatac.C!ml". Would you please contact Microsoft again to fix the problem?
Is there a workaround?

Thanks,
Karsten

Yup! My Windows 11 Defender finds Win32/Sabsik.FLA!ml in it.

SOP update.

Hey folks,

Unfortunately there is little I can do about this. There is no workaround.
Defender does not like programs that manipulate the BCD, EFI or firmware entries.
These are things that Grub2Win must do to function properly.

I contact Microsoft support frequently on this issue.
In this case I cannot, because Microsoft requires information from the actual failing machine.
Mine is not failing this time around, so I can't submit a report, since I don't have the data..

Because your machines are failing, I suggest that you submit a report to Microsoft here:

I will also attempt to submit a report when I get a false positive.

Thanks,

Dave
