Hello @DoctorBlythe, 

Welcome!

1. Kaspersky Total Security (KTS) v21.3.10.319 (m) - is Kaspersky's old version, it would be good to check the issue with Kaspersky's new release: Kaspersky Plus, the upgrade is free & is *like for like*, Kaspersky Plus can be downloaded from: https://www.kaspersky.com/downloads#update-product. Read: Kaspersky: Basic, Standard, Plus, Premium - info & FAQ, by Danila T.

• *Make sure (you) save the KTS Activation code in (your) MyKaspersky account before upgrading* & AFTER the upgrade, make sure to sign-into the Kaspersky Plus application so it synchronises with (your) MyKaspersky account. 

Please share the outcome with the Community, when it's available? 
Thank you🙏
