trend micro pay guard mobile app not working

I cannot open my Trend Micro Pay Guard app. I've been using it for years and now I can't open it. Please help and advise how to fix it.

If you tell me which platform (Windows / Mac / Android / iOS) and any error message you see (or what happens when you try to open it), I can give you step-by-step instructions tailored to your device

My trend is not working, can't scan my android?

Hi there,

Sorry to hear your scan isn't running — let's get this sorted out.

A few quick things to try first:

1. Make sure your Android device is connected to Wi-Fi or mobile data, since a scan needs an internet connection to complete.
2. Clear the app's cache: go to Settings > Apps > Mobile Security > Storage, then tap Clear Cache.
3. Restart your device and run the scan again.

If it still won't scan, this guide walks through what to do when a scan stalls or won't start: Trend Micro Mobile Security scan hangs on Android

To help narrow it down further, could you let us know:

1. What happens exactly when you try to scan — does it not start at all, or does it start and then stop/freeze?
2. Is there any error message on screen?

That'll help us give you more targeted steps. We're happy to help!
