Looks like you got the "HN hug of death".

FYI, having used byethost for free hosting before, I don't believe "securesignupoffers" itself is malware. It's what accounts which have been suspended or don't have a valid index page redirect to by default.

What happened is that someone set up a bunch of accounts on the host for malware/phishing/spamming/etc., and those URLs were used by malware. The host has rightly deleted those accounts, causing malware which forces the user into visiting the original URL to be taken to securesignupoffers instead.

There are many better hosts; you might try Github (via their .github.io mechanism), or if you're willing to pay a very small amount, something like nfshost.

Please public your tutorial anywhere for now.
