Thanks for the tip @harlan4096 While a free upgrade path from KTS to Plus exists for eligible licenses via the Kaspersky site, why isn't Kaspersky proactively notifying users in-app or via email? I've faced multiple issues with my three KTS licenses purchased last year (2025), only discovering they're now legacy and lacking full support requiring replacement to resolve compatibility problems like Teams blocking. This feels like a missed opportunity, as online forums and reviews show widespread customer frustration with outdated KTS features and support. It's a shame, as proactive communication could retain loyalty and prevent unnecessary churn.

Good morning. I haven't received the two-factor SMS for more than a week. I've already changed my phone's SIM and I'm having the same problem: I can't log in to my accounts without that code. I have already sent the incident number several times to Kaspersky support and have not received a response. How can I fix this problem? Best regards.

Buenos días. Llevo más de una semana sin recibir el SMS de doble factor. Ya cambié la SIM de mi teléfono y tengo el mismo problema: no puedo iniciar sesión en mis cuentas sin ese código. Ya he enviado varias veces al soporte de Kaspersky el número de incidente y no he recibido respuesta. ¿Cómo puedo solucionar este problema? Saludos cordiales.

Можно, но лучше в безопасном режиме. И проверить с помощью KVRT. Или загрузиться с внешнего носителя и опять же проверить этот диск с помощью KVRT.
