The 'World's Greatest Anti-Malware Software' is the spurious claim being made by Malwarebiter, which just so happens to sound an awful lot like Malwarebytes which could perhaps justifiably lay claim to that accolade. Take a look at this forum and you will see that Malwarebytes is a very valuable tool for discovering just what nasties are present on your computer, and for getting rid of them. Malwarebiter, on the other hand, is most certainly nothing of the kind.

Malwarebiter, if you hadn't guessed by now, is a prime example of the Rogue Anti-Virus genre, identifying perfectly legitimate files as malware and ignoring those malware files that do exist. Indeed, the Malwarebiter website (which DaniWeb advises you not to visit, for obvious reasons) will distribute a Zeus-family Trojan by way of a drive-by exploit that is delivered in either Java or PDF format. According to Malwarebytes researchers who looked around the site from within a sandboxed labs-based environment "traffic analysis from our visit revealed “roe.js”, a file containing javascript. Upon further inspection the file revealed an embedded iFrame object that links to a rogue IP hosting the Blackhole Exploit Kit, a somewhat funny outcome to visiting a supposed anti-malware site".

Malwarebiter is still showing up in Google searches, although Google does helpfully suggest you might be searching for Malwarebytes instead, but the Facebook page which had more than 25,000 'likes' has been closed down.
