It is agreed that the customers expectation is that they have bought the software with the right to use until they decide that they do not want to use it any longer. In reality, the way McAfee and others do it is to get you to purchase the product with a use license and if you do not renew it then it is shut down and can not be used. I have used McAfee before and did not have that problem. The scan worked but I just could not get any of the updates to stop the new viruses.
I have used Norton Anti-Virus and they do not shut it down and you can get the new virus definition files. The only thing that you can not get is the new Virus Scan Engine. The issue here is that if the latest virus definition file requires the new scan engine then you need to upgrade.
I have learned the hard way I pay the fees needed to make sure that I do not have viruses on my PCs. It takes more time than it cost to purchase a good Anti-Virus program and make sure that you are protected.
You need to decide what is more important the principle of what you feel is your right or the protection of your PC.
My son may have the right idea. He has moved to MAC since they do not have as many problems with virus and popup as Windows. He went to college and he had to rebuild his PC 3 times in the first week since he was attacked by a virus the moment he attached to the college network. He had Norton but I do not think he was updating the Virus Definition File regularly. They put the latest Norton on and he had a lot less virus problem but he had popups like crazy. The people having problems were those with Windows and the people that had MACs di not. He has had his MAC for about 2 weeks and he has not called with a problem since.
I liked him using the Windows PC, that meant he called more often.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
