File submit failed for malware analysis.

I have an English learning software that was recently alerted by Microsoft Defender as potential malware.

When I submit it to Microsoft for analysis as requested. The submitted file is in zip and rar format with password set to "infected".

I have submitted 8 times, using 7zip, bandzip, rar software package, password is in accordance with the requirements. But each time the analyst replied, "Submitted file password is non-standard, please submit a file with password 'infected'"
