If you need to install an antivirus program on your computer, all you need to do is to go to the developer’s official website and locate them and click on the download link for the version you are interested in.
In this way, the online installer of the antivirus will be downloaded in the computer. “Online installer” means a small file through which, once started, you can download and install via internet the actual antivirus program, which consists of a file much larger than the online installer.
But the limitation of the online installer, the word itself says, is necessarily having to have a computer connected to the internet in order to proceed with the complete download and installation of the antivirus on that computer. Which returns inconvenient if the PC in question does not have access to the network.
Here then that in this case you have to resort to the offline installer of the antivirus, or to the actual installation file through which you can completely install the program without the internet connection.
Given that some antivirus companies sometimes make it particularly difficult to download the offline installer, here we go to see the links of download offline installer of the most popular free antivirus for Windows.
