The Internet develops rapidly, and together with its advantages, new problems come to us. For example, prohibit access to some sites from a home computer. You are a good parent and want to close the site from viewing or several at once. Maybe you are a responsible worker and do not want your employees instead of work "hung" in social networks. Causes can be different, and the output one is blocking access to some sites.

There are several ways to block sites. There are less effective to close access to some sites on one computer. Others are more extensive. They allow you to block sites on all devices that are connected to your router: computer, laptop, phone, tablet, etc.

Consider the easiest way to lock on one device, but in all browsers. In order not to open certain sites, for example, "classmates" or "VKontakte", it is enough to change the "hosts" file. This system file can be changed manually and access to the specified files will be closed.
3
On behalf of the administrator, run the standard Notepad program. To do this, find it through the Start menu and click on the program name of the right mouse button. In the open menu, select "Run". In Windows 8, simply type the word "notepad" on the initial screen. Not in the field, but just like that. The input field will appear. The list, click "Notepad" with the right mouse button, then select "Run from the administrator."

In the notepad in the File menu, select Open, go to the "C: \\ Windows \\ System32 \\ Drivers \\ etc" folder. Open the Hosts file (file without expansion). If it is not visible, then at the bottom of the window, find the type of files, set the display of all files.

A file will open in the notepad window, in the contents of which you need to add rows for those sites that you decide to block. For example, you need to block the site "Vkontakte": Specify the letter name of the "vk.com" site, without specifying "HTTP", and the IP address "127.0.0.1". Now save the HOSTS file. Everything, more this site will not open, it is blocked. You can add more strings with IP addresses known to you, which must be blocked, or make redirection to another site when opening the specified one. For example, enter in the string "93.158.134.11 ovnoklassniki.ru". "Yandex" will open instead of "classmates", because Its IP address is specified. Save the modified file, restart.

This very good way has a flaw. If someone owns information, as you can block the site, first of all, will review the "hosts" file. Use another efficient way to block sites using the OpenDNS service. Using it requires understanding and some experience, but can master the novice user. Start registration on OpenDns Home.To use unwanted site filter for free.

On the next web page you will be offered links to read English instructions. This is necessary to block sites on the computer. Even if you do not have enough of these languages, open it to go to the next page. Now, to change the DNS on your computer, find in Windows Network and Shared Access Center. In the list located on the left, go to "Changing the Adapter Settings".

Right-click on an internet connection, select its properties. Now select TCP / IPv4 in the open connection component list, click "Properties". It remains to specify the DNS, which are listed on the OpenDNS Home website, namely: "208.67.222.222" and "208.67.220.220". Complete the work by pressing the "OK" key. After changing the DNS, it is desirable to clean its cache. In the command prompt, type "Ipconfig / Flushdns", start it on the name of the administrator.
There was an unpleasant situation - the site does not open, and you did not blocked it. So, most likely "worked" the virus and included in the list of unwanted your favorite site. You can also correct this situation with editing HOSTS file. View it and delete unnecessary lines with site addresses.
