Windows Recovery is a scareware which masquerades as a system performance optimization tool. Belonging to the FakeSysdef trojan family, it comes in many names including HDD Defragmenter, Check Disk, Windows Repair, Windows Restore, Windows SafeMode, Windows Fix Disk and Windows Recovery. It uses a variety of fake warning alerts about non-existent errors in computer hard drive, memory and Windows registry to try and cheat gullible users.
This rogue optimization software disables Windows Task Manager and Quick launch bar. It also hides All Programs, My Documents and Administrative Tools menu items to confuse and scare the victims.
After continuous bogus error messages, the system is forcibly restarted every few minutes. On restart the rogue software runs a scan automatically and declares finding of multiple errors. The desktop background is blanked and the unclose-able Windows Recovery window hogs the focus.
