4.0.1 core.jar Flagged as Trojan on Windows 10

[Mitch-at-Beaudry]

Description

After downloading and unzipping Processing to the Downloads or Documents directories on Windows 10, running <processing.exe> does not launch the software. No logo, no PID in the Task Manager. Upon further inspection, it appears Windows Defender Safe Screen is identifying the <core.jar> file as a Trojan and "quarantining" it.

It appears nearly identical to this closed issue from Processing 3.3.7 back in 2018.

Expected Behavior

Processing 4 launches after double clicking <processing.exe>

Current Behavior

Processing 4 does not launch

Steps to Reproduce

1. Download Processing 4.0.1, Windows (Intel 64-bit) on a Windows 10 machine
2. Unzip the downloaded file to the same directory (presumably Downloads)
3. Open the unzipped directory and double click <processing.exe>

Your Environment

• Processing version: 4.0.1
• Operating System and OS version: Windows 10 Version 10.0.19043
• Other information: Reproduced on two separate machines, one of which was factory reset.

Possible Causes / Solutions

No amount of setting changes in Windows Defender allowed the <core.jar> file to remain intact for more than a few seconds before being quarantined. My workaround:

1. Move the unzipped Processing directory to the machine's "Program Files" directory
2. Copy <core.jar> from the zipped directory into the new directory
3. Run <processing.exe>
   It seems that the admin permissions of "Program Files" circumvents the Windows Defender Safe Screen process from deleting the <core.jar> file.

Apologies, looks like this is a duplicate of issue #541
