Recently Kaspersky Antivirus decided to do an automatic update/upgrade of the Kaspersky Antivirus from version 20.0.14.1085 to version 21.1.15.500. After the automatic upgrade/installation to the new Kaspresky Antivirus version (21.1.15.500) I get a Terms and Conditions screen that I have never had before. No matter what I do (click on accept or not, close the screen etc) Kaspersky Antivirus continues and then apparently removes my valid/legal license (95 of 365 daysfor 5 devices remaining) and then says that there is no license available and asks me to add a license again. When I do this, and enter the valid/legal license key (95 of 365 days for 5 devices remaining) that Kaspersky Antivirus 20.0.14.1085 was using before the automatic upgrade I get an Error saying "The activation code does not apply to this application" No matter what I do, I can not use the license key (activation code) to activate Kaspersky Antivirus 21.1.15.500. I have tried a couple of things to get the license key (activation code) to work. I have uninstalled/removed Kaspresky Antivirus via Software/remove programms or via the Kaspersky Antivirus removal tool. I have reinstalled different versions of Kaspersky Antivirus 21.1.15.500 but nothing works. The only thing that works is installing Kaspersky Antivirus 20.0.14.1085... when I do that and enter the license key (activation code) again the Kaspersky Antivirus version 20.0.14.1085 accepts the license key (activation code) and starts working like it has worked for the past 270 days. After that I can update the database of the Kaspersky Antivirus 20.0.14.1085 without a problem. But then after a while Kaspersky Antivirus 20.0.14.1085 upgrades it self automatically again and I have to redo the whole process. I can not choose to stop the upgrade, to disable the upgrade or anything else to stop the upgrade from happening. So my question is, can someone PLEASE help me with this. Can someone either help me so that I can use my license key (activation code) with Kaspersky Antivirus 21.1.15.500?? Or can someone help me with Kaspersky Antivirus 20.0.14.1085 to stop it from upgrading it self??
