transferring avast pro to new computer

Hi I bought and paid for avast pro on my old Computer, how do I put the same version on my new computer, any help would be appreciated. Dave

If you still have your registration key I believe you should be able to use that once you install avast pro on your new system, enter the old key and it should be valid for the remainder of the period.

However, I don’t work for Alwil, so it would probably be best addressed to either sales @ avast.com (without the spaces) or whom you purchased your pro license through.

If you don’t use the old computer anymore, then yes - just install avast! on the new one and enter the (old) key.
If you are using both the computers now, you should have 2 licenses for avast!.. i.e. you should get a new key.
