SUSE: 2020:3790-1 Moderate: clamav Denial of Service Update Fix

This update for clamav fixes the following issues: clamav was updated to the new major release 0.103.0. (jsc#ECO-3010,bsc#1118459) Note that libclamav was changed incompatible, if you have a 3rd party application that uses libclamav, it needs to be rebuilt. Update to 0.103.0 * clamd can now reload the signature database without blocking scanning. This multi-threaded database reload improvement was made possible thanks to a community effort. - Non-blocking database reloads are now the default behavior. Some systems that are more constrained on RAM may need to disable non-blocking reloads as it will temporarily consume two times as much memory. We added a new clamd config option ConcurrentDatabaseReload, which may be set to no. * Fix clamav-milter.service (requires clamd.service to run) Update to 0.102.4
