Trend Micro runs continuously when I plug in USB devices

Hi Frank,

Did you put scanning in archive files on?
Did you run a full scan already on those devices?
Witch program exactly is doing that huge CPU use?
What is the version of your OS and TM?

Kind regards,
Tom

Tom - thanks for your response.  Here is my reply to your questions.

1. I don't understand "scanning in archive files" - can you clarify.   
2. I have run a full scan on the devices with a clean outcome, i.e no threats 
3. Task Manager shows the program with the huge CPU use is Trend Micro Anti Malware Solution Platform (which is the same program as when I run a regular TM scan)
4. OS is Windows 10 Home and TM Internet Security 11.0.1186

By the way, when I disconnect the devices in question, TM continues to run as I originally described, and continues even after I shut down the PC and restart.

Hi Tom, thanks for helping us collected the information that we needed. 

Hi Jim Franks, thanks for trying our new Community! 

To help you further with this problem, could you try the following steps and let us know how it goes:

Step1. Disconnecting your USB devices

1. Plug in USB devices first. (And the high CPU usage issue should happening.)
2. Disconnect your USB devices.
3. Reboot your Computer
4. Wait for 10 minutes.
5. Check your task manager to see if high CPU usage issue still persists.

Step2. To specific which hardware or software on your computer is the impact factor.
Please follow the instruction below to do this with The System Configuration window:

1. On your keyboard, press the Windows Windows Key + R keys.
2. In the Open field, type "msconfig", then press ENTER. The System Configuration window should open.
3. Click the Services tab.
4. First, tick "Hide all Microsoft services"
5. Uncheck (Stopped) all items except "Trend Micro Inc.". 
6. Click the Startup tab.
7. Uncheck all items except "Trend Micro Inc.".

10. After rebooting, please confirm if your issue still persists.

Don't forget to return the default settings after the confirmation. If the problem is solved by above settings, we need to tick the Service items back one by one to specific which hardware or software on your computer is the impact factor.

Step3. Check if the problem persisit after changing the scan settings

1. Untick "Scan for threats when opening, saving, or downloading files"
2. Check if the same symptom occurs.
3. If the problem solved, tick "Scan for threats when opening, saving, or downloading files" again.
4. Untick the option "Enable real time scanning for compressed files (like ZIP files)" this time to see if the problem persists. 

Don't forget to return the default settings after the confirmation.

Linda  - thanks for the workplan.  I did Step 1 and confirmed that problem persisted. Before going to Step 2, I decided to reinstall TM per Tom's suggestion.  This appears to have resolved the problem.  But note that I did a TM reinstall back in January and the problem resurfaced, so I'm not 100% sure this is permanently fixed.  However, there is no point in proceeding with your instructions as there's nothing to fix, not yet anyway.  If that changes I will go ahead with your instructions and follow up with you.

Hi @Jim, thank you for the reply.

I understand that after reinstalling, everything seems back to normal. Will it be fine if you continue to monitor the behavior of your Trend Micro program? If the problem appears again, please proceed the instructions that I mentioned last time and let us know besides plug in USB devices, what actions have been taken before the problem happened. Thank you!
