For a week someone has been logging into my webserver. Yesterday I mentioned this to the hosting company. They tell me to use an "IP blocker".
I am doing that, but today I looked for more logins. The IP logging int is 37.201.196.78 (that's not my IP). Today I searched more info about this IP with Zenmap:

One more thing, I think they have also to put a "thing" on my hard disk, because today I updated a page on my webserver and two minutes later, I see this in my comments moderation panel:
Can anyone explain what can I do using simple terms?
