Bitdefender Trafficlight is a free extension for your browser, that will help you when you use a search engine.
Scammers exploit search engine results. When you search the internet for something, the bad guys are trying to predict what you’re looking for. If they can game the system well enough, they rise to the top of certain search results so that you’ll encounter their poisonous websites during your searches.
There are many free helper programs that will check your search results, as you use a search engine. I like Trafficlight the best for this, as it is light on your system, and free. After you add this to your browser, it will block many fraudulent websites as you search, and it will put a ratings marker next to all of your search results. A green checkmark means it is a safe enough website to visit. But a yellow or red warning marker means you should avoid that item.
Trafficlight should work with most search engines and changes very little on your computer. There are others like it out there, with similar protection. Norton Safe Search and DuckDuckGo also have browser extensions you can try out. Just understand that they will change your default search engine to theirs as you install them.
