Hiderun_x86.exe suddenly considered a virus?

Hi,

I wonder why some Antivirus programms suddenly start to recognize Projects\Tools\Common\c86\hiderun_x86.exe as a virus. For example:

I guess this file is essential for WinPE, is there a documentation what it exactly does? And why do antivirus programs now detect this file as malware?
