Signed = 1
SignedInvalid = 2
Unsigned = 3
FailedToObtain = 4
WeakHash = 5, where the MD5 is used as the hash algorithm.
Unsupported = 6, which means the signature was not calculated.
InvalidCVE2020_0601 = 7, which means the executable is malicious and is trying to exploit the windows vulnerability CVE2020-0601.
Deleted = 8, which means that the file was deleted by the time the agent tried to calculate the signature.</p>
