How to block unwanted websites on the internet ?

Answer 1

Do you want to block them for yourself or someone else?

You can block them (or at least minimize their potential problems) by adding the URLs of the sites to the restricted web list of Internet explorer:

Tools menu -> Internet Options -> Security tab. Then, click on Restricted sites, click "Sites" and add the sites you want to restrict. You can increase the level of security to what you want.

To block sites for other people, you may have to purchase an Internet gateway (firewall) if you don't have one. Netgear allows you for example to build a list of URLs that will be blocked if you try to access them. This is probably the easiest and safest way to block them.

Answer 2

Go to Tools, hit Internet Options, go to Security, and click restricted sites.

Answer 3

Get a toolbar with a built in pop up blocker or download Mozilla Firefox and that should do the trick

Answer 4

Easiest way is the windows HOSTS file.
