Trend Micro Maximum Security is slowing some of my applications/programs on my PC.  This problem started with most recent Windows 11 updates (Few weeks ago).  Here are some example of applications/programs affected : CCLeaner, File Explorer, Clear Event Viewer, SolSuite, etc... I have to stop Trend Micro to get it back to normal speed!!! 

Any ideas???

Hi @giguerejeanmarc,

Thank you for sharing your experience here in our community. Kindly ensure that you have the latest version installed on your machine. 

To check if your Trend Micro program is updated, you may follow the steps on the article below:

Check Trend Micro program version on Windows

Let me know how it goes. 

I have the latest version: 17.8.1145. I also forgot to mention that I have the same issue with my wife's PC which is running under Windows 10.  She also has the most recent Trend Micro version. Both of us have to turn off Trend Micro if we want to use these applications and/or programs "normally".

It seems to be a "conflict"  between recent Windows 11 and Windows 10 latest updates ( over the last few months).

This is really frustrating!!!

Any help would be welcome...I don't want to move to an other provider!

Hi @giguerejeanmarc,

I can say that it's not normal behavior. Can you check the CPU usage to see if Trend Micro is at a high level? Can you check it out? ​ 

To check for high CPU usage on a computer, you can use the following methods:

1. Open the Task Manager using these keys Ctrl + Shift + Esc
2. Go to the "Performance" tab.

The CPU usage will be displayed as a graph; if the computer has high CPU usage, the chart will be primarily red.

I hope to hear from you!

I checked the CPU usage and it is not showing a high level (the chart is green).  I still believe that there is a "conflict" with Windows 10 and 11 updates and major Trend Micro updates as well.

For your info, I have been using Trend Micro and its predecessor (PC-cillin) for over 20 years.  I have also been a Trend Micro Beta tester for many years, as well.  I can recall seeing the same problem a few years back and Trend Micro specialists had always been able to find a solution (solve the mystery) ! If I remember properly, I think it had to do with conflicting "Scripts" ???

Let me know if you have an answer/solution for me.

I've just checked and I have the latest updates for my Maximum Security license.

I also have a miserably slow computer since the last major upgrade. There is clearly a conflict with Trend and the latest Win10 release.

All programs are now slow to load. Example: Irfanview used to load the program and then load a picture in less than 1 second. Now, each operation takes 30 seconds to 1+ minutes. Same for Office 365 programs Word, Excel, Powerpoint despite CPU and Memory performance / usage not excessive.

Not impressed with your software and won't renew if a solution is not found soon.

Hi @giguerejeanmarc & @w ,

May I know if you have tried restarting your Trend Micro Components using the Trend Micro Diagnostic Toolkit.

To open the Diagnostic Toolkit:

- Window + R

- On the Run Window, type in "supporttool"

- Once you have the Diagnostic Toolkit opened, click (C) Uninstall Tab

- From (C) Uninstall Tab, click (5) Stop All Components

- After at least 30 secs, click (4) Start All Components

- Check the Trend Micro icon on the system tray, it should say Starting your protection

- Observer if you will still have the same issue.

Yes, I did, once or twice. Unfortunately it did not resolved this issue.  I also tried to uninstall and reinstall Trend Micro, but then again, it didn't work !!!

I tried this on my wife's PC (Windows 10) and same result: problem is still there!!!

Hi @giguerejeanmarc 

We completely understand your confusion regarding the latest update. Could you please verify that there are no pending Windows updates on each device? When Trend Micro releases the 17.8 upgrade, Microsoft also releases their Windows update. If there's an outstanding Windows update, the functionality may be affected, as both Windows update and Trend Micro often depend on each other for better performance.

We'll await for your response!

Hi @giguerejeanmarc​, 

May we ask if we can perform troubleshooting on your computer and collect debug logs in case it needs to be forwarded to our development team?

Awaiting your response. Thanks!

Yes...we could proceed with a troubleshooting!

Hi @giguerejeanmarc​,

It's great to know that you're okay with this investigation. We will send you an email in regards with the details of our scheduled support. Thank you for your cooperation! 

I have the same problem since a week ago. I've tried everything... all that works is turning it off.

Hi @sattlerpantha ,

We will further investigate first and gather the necessary details so that we can pinpoint the cause of the issue. We apologize for the inconvenience , and thank you for your great patience.

On December 12, I spent over an hour with someone from the support team.  As of today, I am still waiting for a response and/or solution for this problem.

I am  very disappointed and as I said in a previous post, I am considering moving to an other provider.  Hopefully, someone will get back to me!

Thank you for your patience.

Thanks for the feedback...hopefully you will soon have a solution for my problem!!!

Hi @giguerejeanmarc,

We will inform you immediately once we have an update.

Thanks!

I too am having the same issue on a new windows 11 laptop. As soon as i install maximum security, the laptop lagged on apps, specifically chrome.

Hi @scott_lewins,

Welcome to Trend Micro Users Community!

Just wondering, have you given a shot at temporarily disabling Trend Micro to see if that helps with the computer lag? If you haven't, you can do that by visiting How to temporarily disable protection on Windows

Let us know how it goes!
