What is the best (more accurate/updated) extension for rank site as safe, dangerous, etc. Something like bitdefender traffic light, web of trust, or norton safe web for understand.
Bitdefender has an option to check search results, similar to McAfee. I prefer BD since it works with any search engine, unlike McAfee, but I don't use it.
One thing to note, if you are worried about privacy, is that the only two I'm aware of that don't send full plain text urls back home (just like smartscreen) are Emsisoft and Malwarebytes. If you trust the company and/or prefer the trade off for security over privacy Bitdefender is probably the way to go, but you have many options. Malwarebytes performs similarly, but slows browsing down more and is more prone to false positives.
