Bug? Windows 10 1511 & B4J "Trojan"

[tchart]

Erel, just to let you know one of my devices upgraded to the latest Windows update last night (1511) and on first start up Defender flagged the B4J uninstaller as a Trojan,

The same here. using windows defender, it detects same trojan as OP mention. But, after it finishes scanning, unins000.exe file remain untouched and it works. How is that possible? It's like the Defender removed only the "trojan" part from the file...

And after awhile, it picked up the B4A uninstaller as well .

I just scanned both B4A and B4J folders with defender - nothing detected on either (win 10 1511)
