Business website can't access

Hello every time i try to access my business website on my laptop, or desktop this keep popping up. We'v safely aborted connection on, greenapplestreasureplace.com.Then it goes on to say because it was infected by URL:Blacklist. Scan your computer for other issues, too? It also does it when i try to access wp-adm. Both keep saying something about URL:Blacklist
Why does keep happening ?
