Hi there! I understand you're having trouble with the TotalAV app not working on your Windows 10 device. Could you tell me a bit more about what’s happening? For example, does the app fail to open, crash, or are certain features not functioning? Any specific error messages or behaviors you’ve noticed would help me guide you better.

In the meantime, I’ll share a few general troubleshooting steps for TotalAV issues on Windows 10:

1. Restart Your Computer: Sometimes a simple restart can clear up temporary glitches.

2. Check for Updates: Ensure both Windows and TotalAV are fully updated. Open TotalAV and see if it prompts for any updates, or visit their website for the latest version.

3. Run as Administrator: Right-click the TotalAV icon and choose "Run as administrator" to give it permission to function properly.

4. Clear Temporary Files: Sometimes corrupted cache or temp files can cause issues. You can clear these by running Disk Cleanup (type "Disk Cleanup" in the Start menu) and selecting temporary files.

5. Reinstall TotalAV: If the above doesn’t help, uninstall TotalAV from "Add or remove programs" in Windows, restart your computer, and then download and install the latest version from the official TotalAV website.

If you have tried any of these steps already or if there is a specific problem like the app not turning on or real-time protection not activating, please let me know! That way, I can dive deeper into more specific fixes for you.

Are you able to tell me what you have tried so far?
