Browser act as a gate for people to access to the internet world, but in the other way round, it is also a gate for the antivirus. No way to say you don’t need a good antivirus firewall software while you have an excellent browser. Yes, browser do provide some simple protection like anti phishing, private browsing and so, but all of the protection are basic. As so, you too need a good antivirus firewall software to protect not only your browser, but also your computer!
