I have an old IBM QRadar SIEM machine that is out of support, but I had to do some root password recovery on it. During this I had to download the Rhe764QRadar7_3_3_20191031163225.stable-7-3-3.iso file which was flagged as having a virus by Microsoft Defender. I wanted to confirm this was expected because the checksum matched what was on your website. The specific flags from Defender were for virtool:python/sharpscshell.a and HackTool:Perl/NiktoSanner.A
