Thank you for reporting this issue. Per your description, if you mean your issue is Maximum Security's files and folders taking up too much hard disk space (e.g. log files, etc.), then a reinstall is a good way to make sure everything is reset. Here's a reference doc for the steps: Reinstalling the latest version of Trend Micro Security program
Please let us know if the solution works for you. If you're referring to something else taking up drive space, it would be helpful if you could provide us the details or screenshots for us to help you further. Thanks!
