[clamav-users] Tips for low memory systems

[Michael Heuberger]

Thanks Kevin

So, how can I set --disable-llvm and --with-system--llvm when I have
installed clamav via apt-get?

I searched for solutions in Google but found none. Any sugestions?

Any chance I can edit that in /etc/clamav/clamd.conf ?

And are there any other tweaks I could do in /etc/clamav/clamd.conf to
reduce it's memory footpring?

Cheers
Michael
