The topic of our article today is how to prevent a program from accessing the Internet. But before answering this question, let's think a little. Still, logic is the best friend of not only a computer, but also a person.
Of course, you can immediately tell how to block the program from accessing the Internet, but until the user himself realizes the need to change something, the recommendations will be useless. Therefore, we start with general questions.
Have you ever wondered why there are more and more various malicious programs (viruses) every year? What makes them feel so free on users' computers? One of the reasons for this is people's attitude towards the security of their own computing system. Rather, completely ignoring the basic rules of working with the Network and applications.
First of all, it is very important to understand that sometimes a program can perform actions that are undesirable for the user, however, not interpreted as malicious.
For example, many people now install the latest Microsoft Office 2013 suite of applications on their computers. But, starting to work with any of them, few people realize that at the time of the initial launch a special module in the background communicates with the company's remote server. Officially - for downloading templates and checking cloud technology, however, there is an opinion that some information about various software used is additionally sent. It is not surprising that many in this situation are wondering how to prevent the program from accessing the Internet.
There are quite a few other applications that (even when the automatic update function is disabled in the settings) periodically communicate with the servers of the developer company. The objectives are pursued for a variety of purposes: checking the validity of a license, transmitting version information, etc. A person who does not know how to prevent a program from accessing the Internet, in fact, loses the ability to control the “behavior” of installed programs. Such a ban is carried out using a firewall - a special program that serves as a filter-layer between the resources of the global network and the computer.
Often it is part of a comprehensive anti-virus protection. For example, KIS, Dr.Web Space, Avira Security Suite contain this module. In addition, the
Windows firewall itself is a firewall, albeit the simplest. Many will be surprised, but with the help of the above applications, the question of how to prevent the program from accessing the Internet is solved in a couple of minutes.
Consider a Kaspersky product. It is necessary on the antivirus icon (red letter V), located in the lower right corner (where the clock is in Windows), call up the menu by right-clicking and select "Settings". In the left list, select “Firewall” - this is where you can prevent the program from accessing the Internet. In the window, click the "Settings" button. Sometimes it’s very interesting to see the list that appears. Suppose a user does not want the AIDA64 diagnostic utility to gain access to the Network at each start. So, in the list you need to find the FINALWIRE group (developer), click on the plus sign on the left to open it, and move all three modules to “Untrusted”. Efficiency while fully preserved. Of course, you should not block access to network applications initially.
