Thank you Yasuhiro KIMURA ,
Isn't it the second scan result ? The second analyse on same file is faster.
Could tou try to restart clamav-daemon and re-do the analyse with clamdscan.
I've tried it on 3 computers, all are above 40seconds

Since some weeks, my clamav (0.100.2+dfsg-0+deb9u1) on Debian 9 64b is very
slow for scanning some files.
It seems that this concerns PDF files. We have this problem with a lot of

I'm using daemon version with default clamd.conf

# clamdscan -v /tmp/esploso_A3TH.pdf
/tmp/esploso_A3TH.pdf: OK

----------- SCAN SUMMARY -----------
Infected files: 0
Time: 185.457 sec (3 m 5 s)

For information, we use a good server (2x Xeon E5-2630v3 with 128Go). I
tried on several servers, the scan is very slow too.

I'll attach one example PDF file. 

Did you have the same problem ?
Is there not a bug ?
