I had my renewal version installed yesterday on my PC Windows7.
Since then the computer has been sluggish.
Please let me know if there are specific setting or other ways I can make it run smoothly again.
Thank you very much for being a long-time Trend Micro product user! For your poor computer performance issue, we suggest you to un-install and install the latest Trend Micro Internet Security version to reset the program and patterns. Here are the reference docs for the steps:
After the above troubleshooting steps, if you still encountering the performance issue, could you provide a bit more detail (e.g. cannot open main console, high CPU or memory usage, it takes 5 mins to opening the browser... etc), so we can understand more background before recommending a solution. Thanks!
