Is TrueCrypt Secure?

If you go to official site for the widely used encryption software, TrueCrypt, you'll see a warning stating that, "WARNING: Using TrueCrypt is not secure as it may contain unfixed security issues". However the reason for this posting simply seems to be that the anonymous developer decided to no longer support the product. An independent audit concluded that the software does have any critical design flaws. See the 2015 report available here. Later in 2015, a Google expert in finding flaws in popular programs determined that there was a flaw in the driver that TrueCrypt installs in Window, that could allow for the system to be compromised.
