My old HP AIO started to slow down a few weeks ago. The Task manager process showed a lot of activity with Trend Mirco with no applications chosen running. Of course, others were running in the background as usual. As it was about 10 years old, I lashed out and bought a new computer this week (windows 11 would not work on my old HP anyway).

I loaded trend micro first and everything I tried to load after, stalled. (bricked is the term I believe) Uninstalling EVERYTHING then loading my key programs without Trend protection is now as good as it gets.

FOOTNOTE. some 15 years ago if my memory serves me correctly, an update by Trend locked out all PCs using it and they then sent a link through about a week later to debug it.

I have read other experiencing simalar problems with Trend lately, so I will now try another product, as I really like the speed I have on My new desktop.........

I think the current change from internet explorer to Edge and windows 10 to 11 is causing software conflicts, that Trend cannot cope with at this time.

Hi @mrayward ,

Since the aforementioned troubleshooting steps that we provided didn't work , you can then proceed in reinstalling the Trend Micro Antivirus app.

You can refer to the link below in using our tool to do the clean uninstallation:

After restarting , you can proceed to downloading the installer on the link provided:

After installing again, check the version if 17.8.1121, replicate the issue by opening affected applications/browser, check if improved (Please take note in the PERTS if there's improvement)

After the update to 17.8.1145, check again if the same issue will persist

Let me know if it helps!
