I wonder if this could get installed on any other set of computers for permanent Anti-Virus.
The issue is not what you could/can do, but rather what you are entitled to do "legally" under the terms of the software licensing agreement.
As an example, in the way back distant past, I did a considerable amount of work for an organization called "Catholic Charities", they had multiple offices and multiple computers in each office. During the course of this work, when I would set up a new computer in one of their offices, I was provided a disc to install Symantec Antivirus on the new computer. This disc belonged to them (Catholic Charities) and was a product covered under an agreement between them and Symantec (could have been a site license, or volume license, or enterprise license, etc.) for which they subscribed to an annual software assurance program and payed a fee to keep the terms and conditions of that agreement current.
Now, could I have brought the disc home and installed the software on my computer...., probably, would it have worked....., probably. Did I have any legal right to the software...., absolutely not. It would have been stealing, plain and simple.
Most commercial software (not freeware) products are all subject to a EULA (End User License Agreement) and the conditions of its' use are defined therein. To summarize, if you didn't pay for it, then it is not yours to use under any circumstances except in special time restricted "Trial" versions which may be available for electronic download.
