Ultra Defragger also known as UltraDefragger is a rogue spyware program masquerading as a Windows disk defragmentation/optimization program. It is a rebrand of the SystemDefragmenter rogue program from last month. Once installed, this rogue program will pretend to optimize your hard drive. Instead it will tell you that it has found numerous security issues and that your hard drive is corrupted by viruses. These fake warnings are used by Ultra Defragger to scare you into purchasing the program.
