On mobile my landing page redirects to weird spam sites?

[John]

Sorry again for being clueless, but I just wanted to check something on my homepage via smartphone and when I tapped the "Enter"-Icon I was first asked to confirm I'm not a robot and then redirected through multiple strange urls and ended up on a dubious German betting page I think? I checked the index.html and everything seems to be in order. I have no idea what's going on. I've definitely viewed my site on mobile before. I'll add a screenshot and two "defused" but potentially harmful links:

Oh, I just realised it's probably a virus on my phone and not a problem with my page? I hope it's alright that I post this anyway, in case anyone here has an idea?

If you think it could be related to your phone (virus or otherwise), check your browser settings for any extensions or add-ons that may be installed that shouldn't be. Also be sure to check your wifi connection to ensure you're connected somewhere secure (at home or a trusted network).

I don't know what you've put on your front page but inspecting it in firefox reveals there's some sort of ad-serving div element approrpriately named AD-FLOAT that serves up ridiculous ads to me if I turn off ublock and privacy badger. i would remove any external sources on your website

Oh, wow. It must have been that hit counter, which was running a javascript. Well, I'm glad I don't have a virus, but that's ... annoying. I removed it and the ads seem to be gone. So, stay away from "counter12(dot)com"...

Can anyone recommend a trustworthy hit counter?
