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:

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.”

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/
Only Windows Defender reports this:

This happened to me :\ .
Windows Defender (with latest updates) no longer reports any issues.
It was a “false positive”.
Thxs for the update. It is always very good to know P3 is not a nasty one

Hi there.
Windows Defender is blocking again Processing 4.0 alpha 2 (15 September 2020)
Platform:
l.
Same here!
Was fine for a while…
:(
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.
And again for Processing 4.0 beta 5 (February 4, 2022)
Damn it !
