Why we need ClamAV? - You have so many private users of Plesk who finance it from their hobby. An additional charge for a complete suite (monthly/yearly) is not an option. ClamAV offers very good protection and is free of charge!
You could integrate this as standard, if a private person or company needs more, here are the chargeable alternatives.

There seems little point in NOT having ClamAV because the PLESK EMAIL SECURITY extension has a warning saying it is not installed.

Plesk is warning us that something is not installed - so why aren't they installing it as standard?

parallels should add clamav integration, that other 3rd party signatures can used also in plesk:

pls parallels standard clamav integration!

Please !

I need ClamAV to secure a NextCloud installation.

ClamAV is needed into Plesk!

How long more?

Yes Please

i also vote for a clamav integration in a free extension!

ClamAv Pleeeaaasseeeeee.
seriously, competition offers the means to deploy it when they are less expensive. Where does the problem ?
A request for 4 years already.not understand this non position statement. Do we deserve this treatment ? We put money so take a stand.

Plesk Team, why don't you close this one? You already have your paid extension.

ClamAV Now!

Found this uservoice on the search for a ClamAV support, voted for this feature!

ClamAV should be a free extension for scanning the web server traffic not just email, and why should it be paid when its a free product.

Thank you for link!

Looking at the fact that Plesk Email Security Pro now includes ClamAV, I assume from a change request point of view, Plesk will see this as solved.
However, it is VERY DISAPPOINTING to see again that Plesk failed to follow the community demand having this as an unpaid extension.
Also, from a security standpoint, I think it is socially not acceptable that they require us to pay for it, especially given the fact that they mainly employ open software for this feature.
In addition, the extension has the drawback that greylisting needs to be disabled, which I think is a bad idea.

Nevertheless, following https://www.lloyd-day.me/migrate-plesk-to-clamav/, there is quite a simple solution if you want to integrate ClamAV yourself.
By not uninstalling DrWeb (free protection of 10 mailboxes), you can even run both in parallel by adapting the information in step 4 (settings for /etc/postfix/main.cf):

With psa_remote and ClamAV, I use:
smtpd_milters = {inet:127.0.0.1:12768, default_action=accept}, { inet:127.0.0.1:3381, protocol=6, default_action=tempfail }
non_smtpd_milters = , inet:127.0.0.1:12768

This setting also helps to avoid issues when DrWeb fails to scan e-mails (happens quite frequently)...

@Dirk I'm sorry, there are too many useless comments.

I think the Plesk's direction is clear: Ok ClamAV, but in a paid and comprehensive feature.

@Ivo
You obviously haven't understood at all what this request is all about.
It wouldn't hurt if you read the comments below to get the full picture.
