Trend Micro wants to ensure you have access to the latest protection all the time. This notification will appear if the program detects that it has not connected to the Trend Micro server for 3 days. Whenever you get this notification, simply connect to the Internet, then update your program by clicking the Update Now button. The protection status will change to Protected.

It is possible that your Trend Micro program is unable to update due to Internet connection being restricted by this feature of Windows 8.1/10. If you have an unlimited Internet connection, we recommend that you turn this feature off. If you are on metered connection (meaning, you pay for each kilobyte of data), you may temporarily turn this feature off then perform a manual update on your Trend Micro program.
