Hi Komir,

what kind of links, to external websites, like shops? More details please, share example.

If your site was hacked cleaning from malware is beyond offcial support, it's always extra paid service.

no, like classic links component/sppagebuilder/?Itemid=240 component/sppagebuilder/ montaza- see hidden content

OK, but on which subpage you have them?

I apologize, I'm confused. Those links find the SEO crawler on the front-end. Is that what you meant?

You have Google Search Console, where you can check which subpage make that "mess", please check it. There is "Check URL" link in "Search/Zoom" icon.

Besides there are Error checking tools/extensions that should help you find Error404 links.

You site has several subpages, don't ask me to check each of them one by one! Sorry, but is not my duty. With proper URL of Page, I can help later.
