Kaspersky Internet Security 2021 – 1 year / 3 PCs – Europe region

Kaspersky Internet Security 2021 in a 3-PC for 1-year licence covers three computers in the same household with a single key. The key is for the Europe region, so it is directly usable from Switzerland. This is a generation earlier than Kaspersky's current range: the program dates from 2021, but the antivirus database updates continue to be provided for the entire licence period, which keeps up detection of recent threats.

What the protection includes

• Three machines covered — the same key activates on three separate computers, manageable from a My Kaspersky account.
• Real-time antivirus — every file opened, downloaded or copied is checked before it runs.
• Firewall — monitors each application's network traffic and blocks unsolicited connections.
• Secure payment — protected browser for banking operations and online purchases.
• Anti-phishing and link analysis — flags fraudulent pages in search results.
• Anti-ransomware — blocks programs that try to encrypt your documents and lets you restore affected files.
• Webcam and microphone protection — access subject to explicit authorisation.

Compatibility

Windows 11, 10, 8.1 and 7 (SP1), 32- and 64-bit, on three machines. Key intended for the Europe region, valid in Switzerland. Each machine must have Internet access for activation and database updates.

Activation

The activation key reaches you by email within 24 hours maximum. Install Kaspersky on the first PC, enter the code in the licence section, then repeat the operation on the two other machines. The 12-month period runs from the first activation.
