This issue arises because of any of the following:


I. The product name was changed when the latest version was released.


Trend Micro occasionally changes its product names to reflect the increasing capabilities and improving antivirus / security technology included in newer versions of the products.


Here are some examples:

• PC-cillin, starting with version 11.0 or 2004, is now known as PC-cillin Internet Security.

• Spam Prevention Service only applies to version 1.0 or 1.1. Spam Prevention Solution is the new name for version 2.0.

II. The product is already obsolete.


Trend Micro does not provide support for End-of-Life (EOL) products and versions beyond what is already available through our Knowledge Base.


Since an EOL product or product version may no longer be compatible with the latest scan engine, pattern file, and other antivirus updates, Trend Micro strongly recommends upgrading to the latest product version or migrating to a new product that fits your needs to ensure your continued antivirus protection and security.
