Just FYI, four browsers are not necessary as well. Avant Browser itself has built-in gecko/webkit and supports ie trident as well. You owns three in one. The second should be opera. lolWhere did the antivirus and phishing alert softwares install on pc or browser.what is the need to install four?
Four antivirus/phising programs are not needed. Avast free with Malwarebytes Pro will monitor the browsers, network connections and email. Previous installed antivirus will be installed under Program Files.Where did the antivirus and phishing alert softwares install on pc or browser.what is the need to install four?
