Honestly avoiding this stuff should be easy since the download page of the fake app itself looks low quality. A harder one would be a website mimicking the real MSI site and redirect their user traffic with DNS redirection, but I don't think this is common for this purpose.
If one never used the real app and just try to google for 'afterburner' the first result wins. Many times people read some articles or watch videos and there is no obvious link to the software, so they try to find it them self.
I have just tried to do it myself, 1st link goes to MSI web site, but 2nd and 3rd goes to other sites (guru3d and techspot) but they have 'Download' word in the page title, so someone who wants to download software as quick as possible would probably choose them.
