A: Antivirus software typically works with your operating system. But there are a few that are specifically designed for use with browsers. As such, they are browser plug-ins or extensions. Such antivirus tools can block access to malicious websites or downloading malicious files.

My favorite is Bitdefender Trafficlight.

Keep in mind that you still need an antivirus for system protection. Again, my preference is Bitdefender antivirus.
