Browser hijacking is likely caused by malware already existed on a user's phone, and might be triggered by ads code on some websites (OzBargain is currently targeted). Googling Congratulations Google User yields predominately Safari on iPhone/iPad issues, rather than issues with the websites.
Here are some instructions from another company that manages display advertising on OzBargain:
The ad network believes that there is a piece of malware that infects Safari users which activates when accessing sites like OzBargain, The Guardian etc. The malware wasn't served by the ad network but instead probably picked up through another site.
Safari users can go to Setting → Advanced → Website Data → <name of site> → Delete the site. Or clear the data from all sites. They also recommend running a malware software like Malwarebytes.
As it seems the ads are possibly the trigger of the malware, blocking all ads on OzBargain should also fix things if the above doesn't help. Go to My Account → Edit → Banner ads: No Ads
For Safari users you can also turn on content blockers on iOS.

Is anyone else having an issue with OzB redirecting to 'fake virus' sites? I find that if I have a bunch of tabs open, inevitably one OzB tab will redirect to DollarCreative and then something saying I have three viruses on my Mac. The weird thing is that I don't click anything to start the redirect (I don't even have the tab open…it just happens in the background). Plus, this is the only site that it happens with. It is only very recent (since Friday) and has probably happened maybe four times in the last three days…but only ever from OzBargain.
It first redirects to a site starting with https:// dollarcreative. com/click… [spaces added]
It ends up at a site starting with http:// mac-safety-check. com.oizfusnvyt.tckdz8w1fino2wn1ua.icu… [spaces added]
Looking around online, it seems that it has to do with rogue ads (eg, here and here )…but is anyone else having this issue?

Safari users can go to Setting - Advanced - Website Data - nameofsite - delete the site. Or clear the data from all sites. They also recommend running a malware software like Malwarebytes.

Thanks for the update neil.
Like most, I prefer not to see ads, but I really quite like OzB and know that a portion is also contributed to good causes, so… Option 1 for me.
Thanks for following up on this, neil. Might be time for me to finally retire Safari for good :)
I've previously been unable to permanently delete all website data using this method, but found that the following steps worked (just in case anyone else has the same problem):
Hey @Katie2014, it may be worth noting that it's not just Safari that's targeted, e.g., "iOS Firefox hijack", "iOS Chrome hijack".
I know from personal experience that our friends on Android suffer from browser hijacking as well, but the nature of this attack may be totally different.
FWIW I use Chrome, Firefox and Safari, and I continue to find Safari an excellent browser on iOS (and the Mac).
Thanks for that info Member 0230. Perhaps I won't retire Safari just yet :)
I'd been using the same three browsers as you as I'd found that competition entry pages sometimes display correctly using one browser but not others (also mentioned by Smalot11), so I'll keep using it for now.
