Some of them: 1. Excessive memory allocations in matcher-ac.c I suggest use this patch: https://wwws.clamav.net/bugzilla/show_bug.cgi?id=434 Or use latest svn version, where committed other Aho-Corasick pattern matcher implementation. 2. Early scanning in libclamav/blob.c I suggest to turn it off. Change #define MAX_SCAN_SIZE 20*1024 to #undef MAX_SCAN_SIZE -- WBR, Anton Yuzhaninov Rambler _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://lurker.clamav.net/list/clamav-users.html
