I'm using the cPanel/WHM installation of ClamAV, and CXS can't seem to find the socket, even when I put the path to clamd in the cxs.defaults file.
I remember a while ago you had to uninstall the cPanel install and install ClamAV independently. Is that still the case?
cPanel / Can't find clamd
Re: cPanel / Can't find clamd
Oops, I found that ClamAV actually wasn't running on my server - CXS was able to find it once I actually got it started and running!
