How to install Nod32 from a URL
Right click on Computer and go to properties. You will need to look at system type and find out if you are running a 32-bit operating system or a 64-bit operating system.
Download the software for the correct version from the links provided by the help desk.
Once downloaded open the zip file and extract all files out of the zip file to a folder. The easist way to do this is to highlight all of the files and right click and copy and then go to a new folder or the desktop and right click and paste. (it is important to include all of the files)
Next double click the MSI to install the software. Go through the default installation and then delete the installation files as they are no longer needed.
