Why good protection matters

At home and in the home office, online banking, shopping, dealings with public authorities and video calls all run on the same computer. That is why an internet security solution protects not only against viruses but also secures your connection to the internet and your webcam, and shields children from unsuitable content.

An example from practice

A family shares one laptop. The parents use it for online banking, the children do their homework on it. With parental controls, each child gets their own time limit, the firewall protects on café Wi-Fi and banking protection secures transfers.

Everyday tips

Good software is the foundation; a few habits make protection even more effective:

• Install updates for Windows, macOS and apps promptly.
• Only open attachments if you know the sender and are expecting the message.
• Never enter passwords via links in e-mails or text messages – open the website yourself instead.
• Use a separate password for every account and enable two-factor authentication wherever possible.
• Regularly back up important files to an external drive that is not permanently connected.

Frequently asked questions about Kaspersky Internet Security 2027

When does the term start?

When the code is activated, not on the date of purchase. So you can also redeem the code later.

Does the licence renew automatically?

No. The licence simply expires at the end of the term. To renew, buy a new code when needed.

What happens at the end of the term?

The program reminds you in good time. After that, the protection features are no longer active until you enter a new code. Your settings are kept.

Can I extend existing protection?

Usually yes: enter the new code in the same account. With most editions, the remaining term is carried over.

Can I distribute the devices freely?

Yes. You can split the licence across Windows, macOS and Android as you like, as long as you do not exceed the number of devices chosen.

Can I use another antivirus program as well?

No, two antivirus programs running at the same time interfere with each other. Uninstall your old protection before installing.

Can I exchange the licence?

Yes, as long as the product key has not yet been redeemed or activated. Simply send us an e-mail.

Will I receive an invoice?

Yes, with VAT shown, with your company address on request.
