You used to can use the previous version keys to activate newer kaspersky I.e 2016,2017 and 2018 would activate a 2019 version of kaspasky so couldn’t you get a cheaper key on eBay ?
Yes. Pop your code in and when your existing licence ends your new one begins. :D
Used to get this free with my Barclays account, but the dropped it now, never had a problem, but do sometimes get emails relating to stuff I may have bought previously, but not from the vendor... spooky...
Had kaspersky for a decade and always been very good. What’s the alternatives for less than £20
