I have bought a new laptop and want to install my current security software onto it from my old one, can I do this or do I have to purchase a whole new load of software for the new one?
Save you license, remove the product from your old computer once that’s done, you can install it on the new one and use your license.
If you got a usual license key - just use it! Same situation like with the windows, that is not bounded to one pc.
But, it can only be used on ONE computer at a time unless you purchased a license that covers several computers.
If it’s a single computer license, it must be removed from one computer before applying it to another.
