Remember that it is not good to have too many websites located in the same web server because if a website gets infected by malware, it can easily affect the online reputation of the IP address and also of all the other websites.

Hi,
thx for your reply
My website is hosted by Ovh mutualised , and other website are not blacklisted.
1 year ago, my website was Wordpress but some virus detected and we remove Wordpress.
And later we change for Prestashop and no virus, but impossible to remove the blacklist 
Sorry for my english not very good,
Best regards,
Christophe
There seems to be lots of malicious activity on that IP, but only avast can say why they block it
avast is notified, so you may recive a reply here
I unblocked water-jump.fr, it was indeed because of the infected wordpress.
Thank you too much !!
Wordpress is deleted, now we have prestashop hosted by ovh with firewall
