⚠️ Crucial Pre-Installation Checklist

Before you download, you must prepare your PC to ensure the activation code works. Free codes often fail if previous traces of Kaspersky exist.

  1. Uninstall Existing Antivirus: If you have any other antivirus (Norton, McAfee, Avast) or an old version of Kaspersky, uninstall it via Windows Settings > Apps.
  2. Download the Cleanup Tool: Download the official Kaspersky Removal Tool (kavremover).
    • Run the tool, select the product you want to remove, and enter the CAPTCHA code.
    • Why? Standard Windows uninstallation leaves registry keys that block new activation codes.
  3. Restart your computer.
