Hi

Upon download of https://github.com/ip7z/7zip/releases/download/26.04/7z2604-x64.msi
our Microsoft Defender for Windows Server alerted, that the file contains Trojan:Script/Wacatac.H!ml

Same with https://sourceforge.net/projects/sevenzip/files/7-Zip/26.04/7z2604-x64.exe.

EDIT: Ah no exactly the same. SmartScreen pops up, but does not name an exact Trojan or anything. In Defender logs, I do not see something either.
