WindowsRecovery Removal and Analysis

by Shanmuga| Tweet This | Google +1 | Facebook | Stumble It | Reddit | Digg |

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.

WindowsRecovery Analysis

A rogue security software such as WindowsRecovery belongs to a family of software products that call themselves as antivirus, antispyware or registry cleaners and often use deceptive or high pressure sales tactics and deliberate false positives to convince users into buying a license/subscription. They are often repackaged and renamed. They do not actually remove malware instead many of them add more malware of their own. They need to be removed immediately from your system.

This fake software hides the All Programs menu item in the Start menu and My Documents folder by running the following commands in the background:

  • attrib +h “C:\Documents and Settings\\*.*
  • attrib +h “C:\Documents and Settings\All Users\Start Menu\*.* ” /s /d

Thank you for the information to remove and unhide files from the fakesysdef trojan. My parents got this virus (in their 70’s and believe everything that pops up and click i 😉 ) I had a feeling everything was still on their computer, but now I have the tools to fix it. I am saving your site because it was very helpful and I didn’t have to search a ton of topics to find the info.
Thank you!
