The Conficker worm computer virus updated itself late Wednesday, bringing a new threat to the millions of PCs currently infected by it.

The discovery was made by Internet security company Trend Micro, who stated in a press release that the ybercriminals behind the notorious Conficker worm may finally be gearing up for more serious attacks.?

As many as 12 million computers could be infected by the worm. Microsoft is offering a $250,000 bounty for its creator.

The worm can be used to steal data from computers. It can also control infected computers to be used in what is called a otnet.The army of computers in the botnet can then be used by a hacker to launch cyberattacks against anything from Web sites to government computer networks.

Such an attack was launched against the U.S. Pentagon in 2007 by Chinese hackers. The Pentagon was forced to temporarily shut down its network and lost an unknown amount of information.

The activation of the Conficker worm came the same day (Wednesday) as reports of cyber spies infiltrating the U.S. power grid. The Wall Street Journal reported that Chinese and Russian spies were behind it, leaving software in the system that could shut down the U.S. electric grid.

Canadian researchers also discovered late last month the Chinese ?hostNet?a spyware system that is being used to monitor and steal documents from 1,295 computers in 103 countries. Among their targets were the Dalai Lama, the media, and hundreds of government and private offices.

Whether the Conficker worm has any connection to the other attacks is yet to be known.

On Oct. 26, 2008, just three days after the discovery of the worm was announced by Microsoft, Chinese hackers created a toolkit that would allow anyone to exploit the system gap. The kit was originally sold for $37.80 but was later made available for free download.

The surprisingly rapid spread of the Conficker worm is attributed to its ability to pass between computers on USB memory sticks. It is also able to invade computer networks. The worm spreads through vulnerabilities in Microsoft? operating system, Windows?lthough an update is now available to repair the vulnerabilities.

The update of the worm was originally suspected to be taking place on April 1. According to Trend Micro the new variant of the worm, known as WORM_DOWNAD.E, runs using a random file name and random service name. It updated itself through P2P communications. The new file was discovered in the Windows Temp folder.

Its effects are yet to be known.

Strangely, according to a BBC report, researchers from the Symantec internet security company said the new update has instructions for the worm to remove virus itself on May 3, 2009, yet a gap in the machine will remain open so that its creators can still control the compromised PC

The “Conficker” worm / virus also known as “Downadup” infection, is actually a virus code programmed in such a way that it can infect your computer and spread itself to other computers across a network automatically, without human interaction.This post provide antivirus support for remove conficker warm from your computer in 5 easy steps.

Step1
If you have a Mac or a Linux machine, breath a sigh of relief; you don't have the right code to be infected. If you're running Windows as your platform of choice, listen up, because this is critical; time is of the essence. You may experience any number of symptoms which are common like loss of Internet connection and loss of local network connection and which are less common like Automatic updates and Microsoft services being disabled.

Step2
Update your anti-virus software. Disconnect your computer from the Internet and scan your system, if you believe you are already infected. To stop the spread of the worm, see step 3. If possible, back up your data ASAP.

Step3
Disable Auto-play in Windows. For Vista: Start > Control Panel > click Play CD's or other media automatically > uncheck Use Autoplay for all media and devices. > click OK. For XP: Start > Run Enter GPEDIT.MSC >
The Group Policy dialogue box will appear. On left panel, double-click Computer Configuration > Administrative Templates > System > Double-click the Turn autoplay off option. The reason behind disabling autoplay is that Conficker can be spread through USB flash drives infected with code that starts on auto-play when the infected drive is inserted into the computer. Disabling auto-play is a good way to ensure against any malicious code automatically gaining access to your computer.

Step4
If you have the Conficker worm, DO NOT DO A SYSTEM RESTORE. Like most malware, Conficker hangs in the restore points and reactivates when you do a system restore. Utilize a decent anti-virus solution such as AVG, Avast!, or Malwarebyte's Anti-Malware. Again, disconnecting your computer from the Internet is critical to prevent the spread of the worm or the continued use of your computer by the worm for devious purposes. Windows Malicious Software Removal Tool can be used to detect and remove the Conficker worm as an option as well.

Step5
Regardless if you are on a network or a standalone computer, download the Microsoft update patch KB958644 (MS08-067) This will fix a security vulnerability that is exploited by the Conficker worm.
