After installing this program and restarting my computer as requested, my computer gave me a “blue screen of death”. After several attempts, always the same crash with the message “Kernel Security Check Failed”.
I went into safe mode to be able to uninstall “Private Secure Disk” but without success.
After much research to find out what had been created at the same time as the installation of this software, I found a residual file “ImgLock.sys” that I deleted.
Everything is back to normal.
Needless to say, VERACRYPT, its competitor, is by far better, more efficient and less dangerous.
