Compressed files created on MAC OS have a folder added automatically named: _MACOSX that contains files that are detected by the Websense/Forcepoint gateways as executable files.
I don't think that these are executable files but having logged a support call the outcome is that this is how it is and it won't be changing.
We block executables to our users by default but don't want to block these MAC compressed files.
Has anyone else experienced this problem and if so have you managed to work around it?
