I have installed Advanced Windows Care 2 and am happy with it. But I don`t know what the Memory Cleaner is for.
It put a small icon in my system tray. I have been able to stop the Memory Cleaner from running at start up and got rid of the icon in the system tray by un-ticking it from the Advanced Windows Care start up menu that I found in the tools menu.
Should I have let the program put the Memory Cleaner icon in my system tray and start it running on start up?
