Everything is fine now, no virus, no spams (cf blacklist)
But the problem Avast still blacklisted my website and so the IP of my server (5.39.80.54) it means all websites who’re on my server are blocked by Avast also but the others antivirus didn’t block them.

DNS report issues: FAIL: While quering domain’s records, some of your name servers didn’t responded. Name servers which didn’t responded:
udp4:213.186.33.199
udp6:2001:41d0:8:2b87::
WARNING: We found different serial numbers on your name servers, it’s OK if you had modified your zone recently.
2001:41d0:8:2b87::: 0
213.186.33.199: 0
37.187.3.197: 2017070603
Having different serials on your name servers may show inconsistencies between name servers configuration (multiple masters), or communication errors (ACL and firewall issues).
Some of these issues are hosting related and should be taken up with tech@ovh.net
