Hi there,

About a month ago, I installed clamav on my debian-based(jessie)linux machine from jessie repository.

*You can find first installed version (slow running one)

root@ruhi:~# apt-cache policy clamav
clamav:
  Kurulu: 0.101.2+dfsg-1
  Aday:   0.101.2+dfsg-1
  Sürüm çizelgesi:
 *** 0.101.2+dfsg-1 500
        500 http://http.kali.org/kali kali-rolling/main amd64 Packages
        500 http://ftp.de.debian.org/debian testing/main amd64 Packages
        100 /var/lib/dpkg/status
     0.100.0+dfsg-0+deb8u1 500
        500 http://ftp.tr.debian.org/debian jessie/main amd64 Packages
root@ruhi:~# apt-cache policy clamdscan
clamdscan:
  Kurulu: 0.101.2+dfsg-1
  Aday:   0.101.2+dfsg-1
  Sürüm çizelgesi:
 *** 0.101.2+dfsg-1 500
        500 http://http.kali.org/kali kali-rolling/main amd64 Packages
        500 http://ftp.de.debian.org/debian testing/main amd64 Packages
        100 /var/lib/dpkg/status
     0.100.0+dfsg-0+deb8u1 500
        500 http://ftp.tr.debian.org/debian jessie/main amd64 Packages

In this try, I had a very serious scanning time problem.
For 110 mb file (this is not encrypted file - normal exe), scanning time is : 1 m 33s (below screenshot)

After that, I installed clamav from the source code that you share on your web page (same version 0.101.2)
The problem of slowing has been solved, but now it seems that not running stable and it is getting very fast results. I want to make sure the results are correct or not. Also you can see that "clamdscan" couldn't find infected files in my zip while "clamscan" could. Compressed files is enabled in my conf file.

Problems :

1) Clamav-daemon couldn't start properly. It starts working on my first attempt and then seems to be disabled and I couldn't make service up.
2) When I want to use "clamdscan" instead of "clamscan" always getting "ERROR: Could not connect to clamd on LocalSocket /var/run/clamav/clamd.ctl: No such file or directory" I can fix this to restart service and make "freshclam" but when I couldn't service up (issue1) I couldn't use clamdscan.
* All problems and conf files are attached

I hope you can help to fix the issues. Thank you
