[clamav-users] how to narrow down the signature database?

[Bond Masuda]

my question is in the subject line, but my goal is to reduce the memory
footprint of clamd. it current takes over 350MB and that's a bit too much.

so, i'm wondering how I can narrow down the signature database to reduce
this memory footprint. specifically, i only care about malware that is
relevant to Linux platform, and not other OSes like Windows. is there a
way for me to reduce the signature database just to signatures relevant
to my OS platform? I'm currently using clamav/clamd on CentOS 6 and my
signatures are updated via the cron freshclam.

are there other ways to reduce the memory footprint of clamd?

thanks,
Bond
