In this manual, several ways to carry out such blocking will be considered, while some of them are less efficient and allow you to block access to sites only on one specific computer or laptop, one of the described features provides much more features: For example, you can block certain sites For all devices connected to your Wi-Fi router, be it phone, tablet or something else. The described methods allow you to make it so that the selected sites are not opened in Windows 10, 8 and Windows 7.
Note: One of the easiest ways to block sites, requiring, however, creating a separate account on a computer (for the user-controlled) - built-in parental control functions. They not only allow you to block sites so that they do not open, but also launch programs, as well as limit the time to use the computer.

Simple site lock in all browsers by editing Hosts file
When you are blocked and classmates do not open or in contact, most likely the case in the virus makes changes to the HOSTS system file. We can manually make changes to this file to prohibit the opening of certain sites. That's how it can be done.
- Run the Notepad program on behalf of the administrator. In Windows 10, this can be done through the search (in search of the taskbar) notepad and subsequent right click on it. In Windows 7, find it in the Start menu, click on it with the right mouse button and select "Run on behalf of the administrator". In Windows 8 on the initial screen, start typing the word "Notepad" (just start the set, in any field, it will appear). When you see a list in which the desired program will be found, click on it right-click and select "Run from the administrator name".
- In the notebook, in the menu, select File - Open, go to the C: \ Windows \ System32 \ Drivers \ ETC folder, place all files in notepad and open the HOSTS file (one that without expansion).
- The contents of the file will look something like that shown in the image below.
- Add rows for sites that you want to locate with the address 127.0.0.1 and the usual letter address of the site without HTTP. In this case, after saving the HOSTS file, this site will not open. Instead of 127.0.0.1, you can use the IP addresses of other sites known to you (between the IP address and the letter URL there must be at least one space). See picture with explanations and examples. Update 2016: It is better to create two lines for each site - with www and without.
- Save the file and restart the computer.
Thus, you managed to block access to certain sites. But this method has some minuses: first, a person who at least once came across such blocking, the first thing will begin to check the HOSTS file, even on my site there are several instructions on how to solve this problem. Secondly, this method works only for computers with Windows (in fact, the Hosts analog is in Mac OS X and Linux, but I will not touch this in this instruction). For more information: the Hosts file in Windows 10 (suitable for previous versions of OS).
