Quick Defragmenter is a fake computer defragmenter and optimization program that hijacks your computer and does not allow you to run any executables. Quick Defragmenter pretends to be a computer error repair and optimization program that scans your hard drives and memory for problems. When installed Quick Defragmenter will be configured to start automatically when you login to Windows. Once started, it will display numerous error messages when you attempt to launch programs or delete files. It will then prompt you to scan your computer with the program, which will state that there are a variety of errors that it cannot fix until you purchase the program. If you attempt to use the so-called defragment tool it will state that it needs to run in Safe Mode and will then show a fake Safe Mode background. As this program is a scam do not be scared into purchasing the program when you see its alerts.
