Czuch: It says that these are used mostly by hackers to have stuff sent to another IP address, or something like that?
That might be the case, but not with that IP address - just make sure they're all to 127.0.0.1 a.k.a. localhost. FWIW, you can clean them manually if you want to (or if there are some to other IPs than 127.0.0.1) by deleting the entries from your hosts file with a simple text editor :)
So I will just ignore these and not worry anymore, thank you again!
