Regarding the security of the Windows operating system, without a doubt one of the most used programs is the Avast antivirus. This is because, although it may not seem like it, it offers practically as much protection as a paid antivirus in terms of threat detection, which is why it is considered one of the best antivirus for Windows 10.
However, the standard and recommended installation for computers, since it is the one that offers the best protection from the first moment, requires an active Internet connection during the process to download the different files. However, you may not have a connection on your computer for whatever reason and still need minimal protection, for which you can use this tutorial.
How to install Avast Free Antivirus on a Windows computer without an Internet connection
In this case, the steps to install the antivirus are very similar to those in the installation of Avast with Internet connection. However, The file to download for this is not the same, since the one downloaded by default from the official Avast website requires a connection. Despite this, they have thought about it, so they have an advanced download page.
To do this, you must first access the alternative Avast downloads through this link to the official website. Once inside you will see a small table with all the download options available, as well as the online and offline installers of the antivirus for the different operating systems, where you must select the offline file for Windows.
Once you have downloaded the file in question, you will only have move it to your computer without an internet connection. For this you can, for example, use a physical medium such as a pendrive or similar, and copy it from one computer to another.
As soon as you have done this, you will only need open the file on your computer without an Internet connection, and the Avast Free Antivirus antivirus installer will open. As with the traditional version, the first thing that will appear will be a window for you to install the software or customize it. Especially if your equipment is low performance or old, it is recommended that click on the customize button and that you modify some of the options, since some, such as the web shield, may not be necessary and, however, if installed, they will be damaging the performance of the computer. In the same way, remember that once installed you will have the possibility to install more extensions.
Then this window will close to begin the installation, and you will be able to see in the lower right corner the progress of said installation.

Does Avast offer the same offline protection?
Once installed, the key question comes, which is whether it will protect against threats. Unlike other free antivirus, the protection is not entirely cloud-based, but also protects locally by downloading some virus definitions. Thus, Unless you connect your computer to the Internet in the future, Avast will work with the virus definitions at the time you downloaded, so it will detect a multitude of possible threats, but if a long time passes they will develop further and logically they will not be incorporated.
Thus, it would be advisable to connect to the Internet from time to time if you want to be really sure. In any case, it must also be borne in mind that by keeping it always disconnected the risk of being infected is much lower except when connecting external devices to the computer, since most of today's threats are transmitted through the network .
