我已安装 ClamAV 0.103 版本。当我手动运行 freshclam 时，我收到以下响应：
ClamAV update process started at Wed Mar 17 15:43:55 2021
daily.cld database is up to date (version: 26111, sigs: 39610058, f-level: 63, builder: raynman)
main.cvd database is up to date (version: 59, sigs: 45649002, f-level: 60, builder: sigmgr)
bytecode.cld database is up to date (version: 333, sigs: 902, f-level: 63, builder: awillia2)
但是当它作为计划任务运行时，我得到了以下响应。仅供参考 - 我最初使用的是 0.99 版本，然后卸载它并安装了 0.103 版本。

你能告诉我这里我遗漏了什么吗？
谢谢。
