1 Hi Michael,
2
3 I quickly tested clamav with option "AlertOLE2Macros" enabled but not
4 worked as expected. ClamAV still marks malicious office attachments like
5 VBA macros as CLEAN.
6 On the other hand gmail detects the virus as soon as i add the file to
7 attachments and doesn't let me send it.
8
9 I envy it.

11 I am happy to hear that next version of spamassassin will have a plugin
12 that can detect office related attachments i hope it will do good job.

14 Thank you.
