It was a typical Monday morning for Emily, an IT specialist at a small but growing firm. As she sipped her coffee and settled into her routine, she noticed that several computers across the office had begun displaying pop-ups and warnings about their antivirus software being outdated.

Kaspersky Total Security (KTS) is the flagship consumer suite. Version number 21.3.10.391 is a specific patch (patch 'a' / 'b') release of the 2021 product line. It was signed and released in late 2020 but remained the standard for most of 2021. Unlike the modern "Kaspersky Standard" (which replaced KAV/KIS) and "Kaspersky Plus" (which replaced KTS), this version strictly used the traditional interface—a dark green and white theme with a dashboard-centric layout.
