Scam Stopper is an extension for Chrome that will alert you when you visit websites commonly used in scams. 

The extension runs in the background and is non-intrusive, meaning it will not slow down your browser and will not cause you any ads. 

As soon as you open a page, it will display a message informing you of the possible scam you might be a victim of. 

The message will be displayed for a short time, but it will not affect you in any way. It can be hidden after reading.
