"Something that can help those users be more secure is switching their browser. XP users often also use Internet Explorer, which can be a severe security risk. Right now, IE 8 is the latest version that will run on Windows XP, meaning that it’s 3 generations old and no longer receives critical updates.
Our advice: If you must keep using Windows XP, switch to Google Chrome. Chrome is arguably the most secure browser for Windows XP, and like Avast, is guaranteed to support XP moving forward."
