Also, Trend Micro program always check for updates every 3 hours.

I'm having the same issues. My CPU goes from 20-45%, I feel like my computer is fairly new and I didn't have this problem when I had my previous anti-malware service (Kaspersky). I also did the whole reinstalling and removal tool and such, as stated in the previous conversations and it really did nothing.

I tried making trend the only startup program and that delayed the spike up to 30 percent cpu usage for about 5 minutes. but the issue still returns. What is so frustrating is that even using the complete removal tool re-installation initially solves the issue but then it comes back

Welcome to the Home Users Community, Fanita and dctorsmurf. Thank you for sending us these information.

Can we check on the Task Manager which process is consuming the highest CPU usage? You guys can send screenshots if that's okay - the Task Manager only with the list of processes (More Details). This is issue can also possibly caused by remnants of other security programs and Potentially Unwanted programs. So keep a look out for those.

Also, you may try adjusting some settings on Trend Micro program. Go to the Trend Micro Settings > Other Settings > On Startup tab, choose Extra Performance. Then click Apply.

By the way, if the CPU Usage for the Trend Micro process is below 50%, it's normal.

Warm Regards...
