BitDefender releases Stuxnet Removal Tool

Standalone utility available for free download on

BitDefender®, an award winning provider of innovative internet security solutions, has today released a free removal tool targeting the Win32.Worm.Stuxnet. Available for free download on, the tool is capable of removing all known variants of the computer worm plus the rootkit drivers that are used to conceal critical components of it.

Win32.Worm.Stuxnet is part of a new breed of e-threats that emerged around mid-July. It infects all Windows-based systems but primarily targets supervisory control and data acquisition (SCADA) systems that run the Siemens WinCC software. It spreads by taking advantage of a multitude of 0-day exploits in the current versions of Windows.

The worm can execute itself from an infected removable medium as soon as the .lnk file on the drive has been read by the operating system. Successful exploitation of this vulnerability results in the injection of a backdoor, as well as the installation of two rootkits that will conceal both the .lnk files and the accompanying .tmp files.

“BitDefender added generic detection covering all variants of Stuxnet on July 19th so we have been protecting our customers since day zero,” said Catalin Cosoi, Head of the BitDefender Online Threats Lab. “However, as part of our constant efforts to help users worldwide in their fight against e-threats, we have also created a Stuxnet Removal Tool. Therefore, users who are not protected by a BitDefender security solution can now also eliminate Stuxnet from their infected systems. The tool can be run on both 32 and 64-bit installations and it will eliminate both the rootkit drivers and the worm.”

The Stuxnet Removal Tool can be downloaded from the Removal Tools section of, a BitDefender initiative for the software security community and a free resource for those interested in their online security.
