New version of AVG TuneUp comes with a significantly improved Sleep Mode, which stops inactive programs from draining your PC. The list shows which applications are draining the most power and with one click, you can select the ones you want to put to sleep. You also have the option to put apps on an Ignore list, which is useful for those programs you really want to keep running in the background. The update also includes a revamped Disk Cleaner which now detects and removes even more leftover and cache files than before.”]
