clamav-base 1.0.2+dfsg-1ubuntu1 (s390x binary) in ubuntu mantic

 Clam AntiVirus is an anti-virus toolkit for Unix. The main purpose of
 this software is the integration with mail servers (attachment
 scanning). The package provides a flexible and scalable
 multi-threaded daemon in the clamav-daemon package, a command-line
 scanner in the clamav package, and a tool for automatic updating via
 the Internet in the clamav-freshclam package. The programs are based
 on libclamav, which can be used by other software.
 .
 This package mainly manages the clamav system account. It is not really
 useful without the clamav or clamav-daemon package.
