Hi Hugo,

I don’t think ClamAV presently supports macro detection and macro blocking in libreoffice format documents, outside of the Microsoft office formats that libreoffice supports.

As a side note, for VBA and Excel 4.0 style macros, ClamAV is getting some improved macro detection in the soon-to-be-released 0.103 version.

Which office document formats exactly are you testing with?

Ged’s idea to write signatures to detect the macros is one possible solution though ideally ClamAV’s macro-blocking feature would work for all document formats. 

Regards,

Micah
