I also don't like running "install" as root.

I have always built ClamAV from source and installed it under
"/opt/clamav-VERSION". This was originally because I didn't want to
wipe out a previous working version until I tested the new version.

But it turns out to have another advantage as well: I can do *all* the
"make" stuff, including the "make install", as non-root. Then, at the
last minute, I do a "chmod -R 0.0" of the new installation, followed by
a "chmod -R clamuid.clamgid" of the "share/clamav/" subdirectory,
followed by setting a symbolic link of "/opt/clamav" to the new
version's subdirectory under "/opt".

Of course this also requires creating the new "/opt/clamav-VERSION"
directory with the proper permissions, changing some of the "make"
options to non-standard values, and now, changing an option or two to
put the systemd stuff into a different place to avoid tying ClamAV to
systemd. (I continue to use cron to trigger updates.)
