Short answer: you cannot rely on a Norton AntiVirus 2005 CD to protect a Windows Vista PC — NAV 2005 was designed for pre‑Vista systems (98/Me/2000/XP) and is not compatible with Vista. This is why older NAV discs and installers fail or behave incorrectly on Vista. (manuals.plus)

Why that happens: Vista changed internal APIs, drivers and the security model, so many XP‑era security products needed code changes to work correctly. Symantec added Vista compatibility in later Norton releases (starting with products after 2006), and Norton/Norton‑Internet‑Security 2010 is an example of a product that lists Vista in its requirements. If you want a Norton product on Vista you must install a version that explicitly supports Vista. (en.wikipedia.org)

Practical next steps (if staying on Vista):

  • Confirm whether the Vista PC is 32‑bit or 64‑bit and what Service Pack is installed.
  • Uninstall Norton AntiVirus 2005 via Control Panel; then run Norton’s Remove & Reinstall (advanced: Remove only) to clear leftover drivers/services before installing anything newer.
  • Install only a Norton build or other AV product that documents Vista support, then run the product’s update tool so signatures are current.
    If vendor support for Vista isn’t available, consider isolating that PC from the Internet or scanning files from a modern, supported system instead. (support.norton.com)

Important caution: Windows Vista reached end of support on April 11, 2017; running an Internet‑connected Vista machine is risky even with the latest AV that once supported it. The safest long‑term fix is to migrate to a supported OS or run modern, supported software inside a virtual machine or newer hardware. (learn.microsoft.com)

Notes tied to this thread: ’s original question is on point; ’s Norton support reply pointing out NAV 2005 is outdated is correct, and ’s search link is a reminder to always verify vendor system requirements before installing.

Hi cbk,

This is Mike from the Norton Authorized Support Team.

Norton AntiVirus 2005 is not supported on Windows Vista and is also an outdated version. For optimal protection you will need to use the latest version of Norton AntiVirus, which is the 2010 version. For more information on Norton AntiVirus 2010, please see the page below.

Thank you,
Mike
