I see some support topics recently about missing installer files, and I wonder if my issue is related.
I created a package, downloaded the .zip file fine. But the installer download was blocked because of malware detected.
I then went into my hosting filemanager, and found out that the installer.php file was missing. Possibly my host also detected malware and pro-actively quarantined the file (not sure)?
The .bak installer file was there, so I downloaded that with FileZilla. Then scanning it with Microsoft Defender, a trojan is detected and the file gets deleted. Below is a screenshot:
I’ll scan my hosting account and WordPress installation, but wanted to make you aware of this as well.
Thank you
