I have got "McAfee Internet Security E card" from my brother.
But the "Warning" in e card says that,
Invalid&Unsupported if sold without Lenovo Idea PC
Only for Southeast Asia Region of Lenovo
So I would like to know that can I use this E card for my Dell notebook?
Technically you shouldn't be able to do this however if you have a Lenovo Idea PC have the Product installed on it first and then Uninstall completely. Now login to McAfee's My Account (https://home.mcafee.com) from DELL PC and try installing there.
Post back for clarifications.!
