ATD-Guard: what is it?

ATD-Guard is a Host manager coupled with a computer connections scanner.

Description of ATD-Guard:

Unlike simple ad blockers, ATD-Guard does not act at the level of your web browser but at the level of the computer which means that it can block not only the connections initiated by your internet browser but also the connections initiated by all programs installed on your computer.

For example :

Programs that constantly send statistics on their use.

The incessant update checks and sometimes their download in the background.

Free programs whose publishers finance themselves by collecting data on your computer and, in general, spyware or viruses that you have accidentally installed or that have been installed on your computer against your will.

Some well-known program editors require a module that runs in the background even when you are not using the software (official reason: automatic update, faster availability if you open a document, etc.). These software keep you connected to their server and transmit data without your having control over its content.

Your computer does not need to notify your printer manufacturer every time you print a page. Yet this is often what happens.

At the level of your browser, you will notice that for the display of a web page your browser sometimes connects to a good hundred domains: advertisements, trackers, statistics, geolocations etc ... All these connections slow down your navigation in large proportions and you will be surprised to find that your internet browsing has become smooth since you blocked all those unnecessary connections.

Scan your computer connections:

Thanks to ATD-Guard you will be able to scan all the connections of your computer which will allow you to filter out anything that is unnecessary or even harmful.

Start the ATD-Guard scanner then start the software to be analyzed. You can see any connections initiated by it and block them if they do not seem justified to you.

The same when starting the computer will allow you to locate programs that start automatically and connect.

Launch the scanner and then display a popular web page. In the multitude of domains displayed, you will find the domain name of the site consulted, then all the rest not always useful. By browsing in this way the websites that you visit regularly you will quickly find everything you do not need and block it. Everything is not always to be rejected under penalty of preventing the website from functioning properly. Some elements of a page can come from another domain than the main domain and be essential for its operation.

There is no risk for the operation of your computer to block connections since a computer can still function without any access to the internet.

There are pre-established lists of domains that are worth blocking. Just load these lists into the program.

What is the Host?

When your computer connects to a server, it is actually connecting to an IP address. For more convenience you do not enter the IP address of a server in your internet browser but a domain name which is in fact a kind of shortcut to this IP address. Your computer will then consult a DNS (Domain Name Server) which will give it the IP address corresponding to this domain name. But before consulting the DNS server, Windows (like all other operating systems) will consult a file called Host to see if there is not a specific instruction concerning this domain name and in particular a redirection IP address . It is therefore at the Host level that we will redirect all the domain names that you want to block to an empty address. 2 empty addresses are generally used which means no access and called localhost which is the address of your own computer.
