我有两个关于 Ubuntu 18.04 的 ClamAV 的问题。
笔记：我最初将这个问题发布在：https://answers.launchpad.net/ubuntu/+source/clamav/+question/691247
1）尝试更新数据库时，它会引发错误：
$ freshclam
ERROR: /var/log/clamav/freshclam.log is locked by another process
ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log).
ERROR: initialize: libfreshclam init failed.
ERROR: Initialization error!
2）如果手动更新，
$ sudo systemctl stop clamav-freshclam
$ sudo freshclam -v --debug
我收到：“LibClamAV 调试：cli_cvdverify：MD5 验证错误”
