How to get rid of ads in windows system

1

Open Windows Explorer and type in C:/Windows/System32/drivers/etc. If Windows isn't installed on the C: drive, substitute the C: for the appropriate drive letter.

2

Double-click on hosts and open the document using Notepad when Windows prompts you. The hosts file tells the system what it should do when specific domains or IP addresses are accessed. This is the file that you are going to edit. If Windows automatically redirects you, or if hosts opens in another program, simply open Notepad (Start -> All Programs -> Accessories -> Notepad) and then go to hosts by clicking File -> Open inside Notepad.

3

Locate the line "127.0.0.1 localhost" or "::1 localhost." Put your cursor at the end of whichever line is lowest down.

4

Press "Enter" to create a new line. 

5.Type in whichever website or websites you wish to block. You can add any site, but you'll will need to preface it with "127.0.0.1".

• To block the website reddit.com for example, just type in "127.0.0.1" followed by a single space, followed by "reddit.com".
  
  
• Add all of the site's domains, especially mobile domains, on new lines. Your computer might block "www.facebook.com", but not "m.facebook.com" if you're not careful. This is an easy workaround for the experienced computer user.
