You've probably switched off Safe Browsing. I wouldn't advise anybody to do that unless they're _so_ sure that they don't need Safe Browsing that when (most likely rather than if) they get infected by Malware or fooled by Phishing they are confident they'd tell everybody they know what an idiot they are.

I have it switched off on my home PCs (but on for work). But then I also don't carry home insurance and when I was flooded I believe my first Facebook message began "This is probably a good time for you to say 'I told you so'" because that seems like the right sentiment.
