Another FREE Security add-on for Chrome - Malwarebytes Browser extension (BETA). It prevents pop-ups, browser hijackers, and browser lockers from harassing you and interrupting your surfing. It also blocks clickbait links and fake news content, stops in-browser cryptocurrency miners, and gives other malicious content the boot. All this while relying on threat behavior patterns.

This is where Malwarebytes Browser Extension can help you:

• Protection from tech support scammers: Blocks browser hijackers, and browser lockers, which are used by scammers to drive victims to call centers that use scare tactics to sell expensive technical support (that you don’t need).
• Faster web page load times: Popular websites download a lot of unwanted content in the background. By filtering out clickbait and ads, Malwarebytes Browser Extension BETA can speed up your webpage load time, saving your sanity and bandwidth.
• Prevents visits to malicious pages: Protects you from inadvertently visiting bad websites that host malware content, steal your identity (phishing), load Bitcoin miners in the background, which slow down your computer, and a long list of other obnoxious behaviors that can make your online experience less than stellar.
• Keeps your privacy private: Blocks third-party ad trackers that follow you around the Internet and target you with the same ads over and over again.
