Windows Defender Antivirus on Windows 10 is reporting a threat with the core.jar file in Processing 3.3.7 64-bit.  
I get the same report on both my PCs with recent updates to signature files.

No threat reports for 32-bit version.

I have submitted this to Microsoft for analysis:  
[https://www.microsoft.com/en-us/wdsi/filesubmission](https://www.microsoft.com/en-us/wdsi/filesubmission)

I have tested this file with a few on-line scanners and no reports of concern.

It may be a false positive.

I will use the 32-bit version for now.

From Ben Fry (a co-developer for Processing):  
“It’s a false positive. Has been happening with recent releases, but it’s always reported as a different trojan. I submit the report each time but never receive any response from Microsoft.”  
Source on Twitter:

I have “excluded” the core.jar file in Windows Defender using the 64-bit version.

The 32-bit version does not give a “false positive” and is available at:  
[https://processing.org/](https://processing.org/)

Only Windows Defender reports this:

Windows Defender (with latest updates) no longer reports any issues.  
It was a “false positive”.

And again with the latest Processing 4.0 beta 1 (August 9, 2021)

It was fine for a few days…

I am getting this as of this morning:

It may be a false positive as it was before.
