How Bitdefender, Norton, and Kaspersky hide the cap

Bitdefender fails if the cap is only in a FAQ. Norton fails if antivirus needs a kicked device. Kaspersky is the control: if its third install worked, do not excuse a silent cap.

Fails that kill antivirus-ranked-2026-devices-2026-09-16-s31

• Paying Bitdefender annual after one phone install
• Skipping the third device on Norton
• Assuming Kaspersky is unlimited because the homepage said so
• Dropping antivirus to stay under the cap

Go / no-go 2026-09-16

Annual only if the device cap and extra-device USD price are written for “antivirus”. Otherwise antivirus-ranked-2026 stays monthly until antivirus fits the included installs.

Install on the second and third device the same day

On Norton, enroll device 1, then device 2, then a tablet. Write which install hits a paywall. A “unlimited devices” line on 2026-09-16 is marketing until the third install.

On Kaspersky, enroll device 1, then device 2, then a tablet. Write which install hits a paywall. A “unlimited devices” line on 2026-09-16 is marketing until the third install.
