No, I don't have a subscription. My system is a bit old. It's running a quad-core Xeon 3Ghz with 4G of RAM. The RAM doesn't seem to be an issue, just the slow loading due to the CPU. It scans a bit slow as well, but that's not an issue since we don't have a high email volume. -- Bowie _______________________________________________ clamav-users mailing list clamav-users@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
