Total Cleaner's ActiveCare analyzes your system and runs common system cleanup and maintenance tools at regularly scheduled intervals. It does things like finding and removing junk files, cleaning the system registry, removing Internet clutter, getting rid of spyware, and defragmenting your hard drives.
ActiveCare works by monitoring key indicators of PC performance, and then automatically runs the repairs your computer needs. It works silently in the background–while your PC is on but not in use–and it only processes actions when they are needed. If you return to your computer during ActiveCare processing, you can either cancel the process or let it continue.
