Learn how to upgrade your Trend Micro program to the latest version. You can upgrade your program for free as long as your subscription is not expired.

Differences between "Renewal", "Upgrade" and "Update":

  • Renewal - extends your subscription/expiration date. This happens automatically after your renewal purchase. Program version does not change.
  • Upgrade - removal of current Trend Micro program then installation of the latest program version.
  • Update - checking, downloading and installing of the latest virus patterns/definitions. This is automatically done by your Trend Micro program every 3 hours.

  • We recommend that you print out this document or bookmark this page before proceeding because you will be asked to restart your computer during the procedure.
  • Some products bundled with new or renewing purchases are not available when you opt to get the free upgrade. These will be made available when you renew your subscription. To find out what products are available when you upgrade, log in to your Trend Micro Account.
