Disk Defragmenter

Disk Defragmenter Description

Disk Defragmenter (DiskDefragmenter) is a fake system defragmenter and optimizing tool cloned from another rogue called Disk Optimizer. Disk Defragmenter can be obtained when browsing malicious websites or it can be downloaded onto a system by Trojans. A fake system scan is then simulated to produce exaggerated results which will scare a user into purchasing Disk Defragmenter's full version. The scan will claim that "11 Errors detected! Defragmentation is required" and then prompt a user to pay for Disk Defragmenter which can apparently repair all the detected errors.

Blocked access to programs such as Task manager or even security websites is a symptom of Disk Defragmenter on your system. Users should ignore all the error reports and security alerts displayed by Disk Defragmenter because they are all fabricated. Do not purchase Disk Defragmenter but have it removed from your system with a choice rogueware removal tool.
