Without the FOSS/OSS community Plesk wouldn't function. You'd be stuck supporting Windows Servers & IIS.

@Admin - you state that trying to intergrate ClamAV is sooo hard. In fact if I wasn't running Plesk and using iReadMail its set as default OOTB (out of the box).

So please - don't spread FUD.

Plesk currently offers two pieces of spying software - drweb and kaspersky, so please implement something more adequte, for example - clamav ;)

ClamAV ist a must have fort Plesk. Please integrate this.

@anonym: Btw. search for Kaspersky and the terms espionage or spying...

Since Plesk was taken over by a financial investor user requirements and user needs, even open standards are obsolete.

New target is the reselling of proprietary overpriced third-party ****. Looks like a squeez out process until all price rises and user disregardment pays back and Plesk is a name from the past.

Open Source SW like ClamAV should be prioritized than paid solutions.

Its not needed. Kaspersky-AV do this perfectly.

@Brujo yeah completly right.

one of the first things I always do on a new Server, is to integrate CLAMAV to Postfix, so I provide antivirus protection to all mailboxes and for all Users for free. In my opinion this must be out of the BOX for Plesk for Basic securit of Mailboxes...

Come on plesk staff, be honest. It's a simple undertaking but it would lower your sales on the paid antivirus solutions. Was that hard to say?

PLESK must be getting a percent from these expensive antivirus solutions they suggest.
There is no other explanation to avoiding ClamAV. I am used to using plesk, but when I see that other control panels offer ClamAV integration for free, I am disheartened..

ClamAV would let us provide antivirus protection to all mailboxes for free.

>> Warden Anti-spam and Virus Protection
This is totally fine to provide some additional functionality of open-source solutions for some fee, but this is not what we need or discuss here.

Open-source spam filtering and virus protection should be provided/supported out-of-the-box by plesk.

Warden Anti-spam and Virus Protection is now in the Plesk extension directory:

https://ext.plesk.com/packages/a0814127-0f74-49d4-afff-6f644f02d612-warden

Full ClamAV support with virus logging!

>> Plesk currently offers two high-quality anti-viruses and other related services like WAF

Plesk currently offers 3 PAID antiviruses with no open-source alternative. There is something wrong with Plesk.

ClamAV must have been added years ago, before you add any paid antiviruses.

Have you tried the Revisium Antivirus extension for websites? https://www.plesk.com/extensions/revisium-antivirus/

It includes fully-functional malware file scanner and also one-click automatic removal in a premium version.

How can we get the falsely blocked emails from the Dr.Web infected directory into our Clients mailboxes?!

With OS can install ClamAV with yum or apt-get.

Better is use Maldet - https://www.rfxn.com/projects/linux-malware-detect/ & extra signatures to better detect malware from PHP files:

Also mod_clamav to ProFTPd that can scan FTP uploaded files with Malware:

As for me, adding a clamav milter wasn't complicated - just install clamp-milter for systemd, configure it and add its socket to /etc/postfix/main.cf - and it works!
It would be great if Plesk would do these steps for you :)
