[clamav-users] Question about .cvd files

1.  bytecode.cvd contains AV signatures written in our bytecode language.  This allows us to have very advanced processing of files for detection.
2.  Malware may not be specific to one OS.  Or malware may be copied from OS to OS.
3.  I don’t think you’d wan to do this, based upon what I just said in #2.
