Sorry, adding more details for reproducability.My original idea was to use maldet, which uses clamscan so whitelisting and path exclusions need to happen in clamav, they don't seem to be passed on to clamscan.
Environment: 4.19.0-10-amd64 #1 SMP Debian 4.19.132-1 (2020-07-24) x86_64 GNU/Linux
The script clamcars.sh (attached) downloads, whitelists, scans and puts the results in "result_<filename>" for each of the eicar files. I can repeat with debug output redirected into the file if it helps.
I am using "clamscan" (used apt-get install clamav) not the daemon (clamdscan), so I do not seem to have clamconf:
# clamscan --version ClamAV 0.103.2/26152/Mon Apr 26 06:04:28 2021Would it help you to look into this if I installed the daemon scanner and repeated the test?
The only config I was able to locate is below. Thanks.

Hi there, On Mon, 26 Apr 2021, Haukur Valgeirsson via clamav-users wrote:I am setting up daily scanning and was figuring out how to whitelist based on file signatures, and decided to use the eicar test files to tune the settings. Used 'sigtool --md5 eicarcom2.zip > falsepossigs.fp' to create the sig to whitelist and proceeded to run test scans and the results were a little surprising:Given your description of what you did I'd struggle to reproduce it. Please give full details of how you are running the scans, the exact unaltered output as you see it, and the output of 'clamconf -n'.
