Using same key for iPhone and Win PC possible ?

Hi to all,
i use payed SecureLine on my iPhone 4s the last two months.
Is it possible to use the same key for a windows pc (OS Win8 Pro, 32 bit) ??
And when, how to insert the key in Avast Internet Security ??

Sorry, but it’s not possible to use the same license of secureline ios in secureline windows.

Thanks for answering - that will be a very expansive thing using both SecureLine for IOS and Windows.
And additionally the fee for Avast Internet Security, wow.
