You are used to using Internet Explorer to visit your favorite sites. The famous blue "e" icon has some better and more secure competitors, Google Chrome is one of them.
Don't worry, the websites will be exactly the same with Chrome or Internet Explorer, only the way to access them changes. It's a bit like if you have a 82cm or 117cm television, the movie will be the same.
The Google Chrome browser is free and compatible with Windows 10, 8.1, 8, 7, Vista and XP. Note that these last two systems will soon be unsupported.
