antivirus: promo-to-list renewal window (2026-09-13)

Compare Antivirus prices the promo-to-list jump for “norton antivirus” in antivirus on 2026-09-13 using Bitdefender, Norton, and Kaspersky in USD. Focus: antivirus. Annual is blocked until the renew date and list price are written, not guessed.

How Bitdefender, Norton, and Kaspersky hide the jump

Bitdefender fails without a written list price. Norton fails if antivirus has no calendar day. Kaspersky is the control: if its promo never ends in writing, freeze the year.

• Prepaying Bitdefender from a homepage badge
• Ignoring list price on Norton
• Skipping antivirus because the promo felt long
• Trusting a chat bot for the flip date

Go / no-go 2026-09-13
