Administration - Installation - Core: ClamAV virus scanner for upload file.

Hello,

I am trying to configure a virus scanner for the files user tries to upload. My goal is to prevent users if they try to upload a virus-infected file. For that reason, I have installed ClamAV on the server. In the ilias setup page, my configuration looks like bellow-



However, I am able to upload test virus file downloaded from eichar.com. Ilias is not preventing me from upload. Am I missing something?

I will be glad if someone can help here.

PS: I have tried this at ilias 5.4 and ilias 6.

Thanks,
