URL Blacklist jquery

Hi.

My friend’s website is marked by avast as a blacklist: https://marketingforce.cc/zapis-na-konsultacje-w-sprawie-kampanii/. The pop-up details say that the blacklisted file is https://marketingforce.cc/wp-includes/js/jquery/jquery.js?ver=1.12.4-wp, which is the core Wordpress file. Is there anything that can be done?

So the only problem is PHP 7.2? Is that enough to be blacklisted?

I’ve reported it and get answer:

Thank you for contacting Avast with your concerns. Our virus specialists have been working on this problem and they informed me that this detection is correct.

Nothing much I/we can do on the forum, only the guys from threat lab can unblock it.

So there is nothing I can do if avast support is saying that it is blacklisted corectly, but they can’t tell my why?

Update/Clean the site and resubmit it afterwards.
