System Defragmenter

System Defragmenter Description

ScreenshotSystem Defragmenter aka SystemDefragmenter is a fake anti-spyware program that is part of the FakeSysDef family and disguises as a legitimate application. System Defragmenter is secretly installed onto a PC before bombarding the desktop with fake security alerts and scan reports claiming the detection of dangerous malware. Victims of System Defragmenter are coerced into purchasing its "licensed version" in order to remove all the purportedly detected malware. Of course this is a scam and victims that encounter security notifications from System Defragmenter should use a legitimate security tool to remove this rogueware completely.

The FakeSysdef family is a big family of threats that has among its members Ultra Defragger, HDD Control, Win HDD, Win Defrag, Win Defragmenter, Disk Doctor, Hard Drive Diagnostic, HDD Diagnostic, HDD Plus, HDD Repair, HDD Rescue, Smart HDD, Defragmenter, HDD Tools, Disk Repair, Windows Optimization Center, Scanner, HDD Low, Hdd Fix, PUP.PC Health Kit.
