I am not really computer literate. I do not know what you mean by changing browsers. I do not know what browser I am using. I need some info!
A Browser is what you use to connect to the Internet to (Browse).
You are probably using Internet Explorer ?
You can search online and download other browsers, like:
1 - Mozilla Firefox
2 - Google Chrome
You do not have to get rid of your current browser. You can use any of them.
