You could install Norton and activate the product. At this point the user interface will tell you if the product successfully activated and how many days are left before the software expires.
If you purchased a 3 PC license, the first date that license is activated is when the clock starts toward its expiration in 365 days. Therefore, when you buy that third PC and activate the last remaining license from your 3 PC license, the third PC will expire at the same time as the first PC license.
You can manage all your copies of Norton Antivirus from one place by downloading Norton Management from the Symantec.com site http://tinyurl.com/9felpej, or as an installation option on the installation disk. You must use this software in order to monitor Norton Antivirus from one location. This software will probably negatively impact computers that already have performance issues.
How do can you minimize the cost of Norton Antivirus?
- Never simply download a copy of Norton; always copy to a disk. Unless you create an installation kit by copying the download to a cd, reloading Norton after a computer crash or loading onto a new computer will be difficult.
- Having a physical copy of Norton, i.e. an installation disk, makes it easy to claim a rebate that requires previous proof of purchase. If you scan the Sunday newspaper for deals on Norton, you can buy a new copy where the cost is free after filing out a rebate form.
