From a web developer: you're talking absolute nonsense on so many levels.

First of all, there is nothing whatsoever in the source code of the site which seems suspect. It's actually extremely concise and fairly well put together for a random landing page. It doesn't even connect to any third-party domains.

Secondly, unless you're using an old/outdated web browser e.g. Internet Explorer 9, there's virtually zero chance of any website silently downloading malware to your "machine/device" (would be incredibly sophisticated if it was able to infect multiple different platforms/devices as well). Any infection would require user interaction i.e. downloading an executable file and running it on your device.

I don't know who hurt you, but you should stop spreading falsehoods about internet security.

Edit: in the source code of the site, there is an extensive list of swear words (profanityArray) which is likely what is triggering some of the over-sensitive "virus scanners" (glorified content filters) into thinking the page is naughty. Ironically, this list of swear words is used by the website to prevent customers from entering naughty phrases into the website's form.
