I am running a new Debian 11 box here. When I run
apt search clamav
It shows 0.103.7 which is newer than 0.103.2
clamav/stable
0.103.7+dfsg-0+deb11u1 amd64
anti-virus utility for Unix - command-line interface
clamav-base/stable
0.103.7+dfsg-0+deb11u1 all
anti-virus utility for Unix - base package
clamav-daemon/stable
0.103.7+dfsg-0+deb11u1 amd64
anti-virus utility for Unix - scanner daemon
For this system, I choose not to run the Debian packages of
Clamav for other reasons. So I am running 1.0.0 on that box as I
installed it via source downloaded from Clam.
You have options.
I will admit that compiling
from source is not for everyone.

It was suggested that: "If FreshClam is failing and you're not sure why, you may run freshclam -v for "Verbose Mode" to see the HTTP request & response details (ClamAV 0.102+)." And that: "[If] running a version of FreshClam/ClamAV lower than 0.103.2? If so, you should immediately upgrade to at least 0.103.2." But am exclusively a Debian Linux site. There is no version beyond 1.0 for Linux. While I installed the code via aptitude, a Debian package installer, I did check to see if there was a later version on https://www.clamav.net/downloads for Linux. There is not. 1.03 is a Windows version.
