Virus Removal
Just what is a virus? Virus means "poison" in Latin, and a computer virus is, well, a computer poison. Computer viruses are malicious software programs that are designed to adversely affect your computer without your knowledge or permission. It is a leech that implants itself on legitimate software and spreads from one file to another. A virus might corrupt or delete data on your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk. Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files in e-mail messages or instant messaging messages. A virus can infect your computer when you are just visiting a website, using a shareware program, or opening a Word document. The list of possible infection points is enormous and covers almost any imaginable user activity.
Conficker Virus Removal:
It is estimated that more than 15 million computers worldwide have been infected with Conficker. Alternatively known as Downandup or Kido, the virus is believed to allow hackers to steal user passwords and personal data, such as banking information. It started spreading in late 2008 and turned infected computers into slaves forming an army of computers known as a botnet. Although the Conficker virus was supposed to get activated on April 1, 2009, and cause a huge wave of distruction in its path, the big attack never took place. Nevertheless, internet security experts emphasize that the threat is real and evolving. Conficker may not have staged the widely anticipated dramatic showdown, but instead has gone on a stealh trajectory and taken up quiet residence in sabotaged machines. It now installs a second virus, Waledac, which engages the infected computers into another botnet specialized in distributing e-mail spam. Look here for possible Conficker virus removal tools.

From Wikipedia, the free encyclopedia
Common name Conficker

Classification Unknown
Type Computer worm
Subtype Computer virus
Conficker, also known as Downup, Downadup and Kido, is a computer worm targeting the Microsoft Windows operating system that was first detected in November 2008. It uses flaws in Windows software and Dictionary attacks on administrator passwords to co-opt machines and link them into a virtual computer that can be commanded remotely by its authors. Conficker has since spread rapidly into what is now believed to be the largest computer worm infection since the 2003 SQL Slammer, with more than seven million government, business and home computers in over 200 countries now under its control. The worm has been unusually difficult to counter because of its combined use of many advanced malware techniques.
Name
The origin of the name Conficker is thought to be a portmanteau of the English term "configure" and the German word Ficker, which means "fucker" On the other hand, Microsoft analyst Joshua Phillips described the name as a rearrangement of portions of the domain name trafficconverter.biz, which was used by early versions of Conficker to download updates.
Discovery
The first variant of Conficker, discovered in early November 2008, propagated through the Internet by exploiting a vulnerability in a network service (MS08-067) on Windows 2000, Windows XP, Windows Vista, Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2 Beta. While Windows 7 may have been affected by this vulnerability, the Windows 7 Beta was not publicly available until January 2009. Although Microsoft released an emergency out-of-band patch on October 23, 2008 to close the vulnerability, a large number of Windows PCs (estimated at 30%) remained unpatched as late as January 2009. A second variant of the worm, discovered in December 2008, added the ability to propagate over LANs through removable media and network shares. Researchers believe that these were decisive factors in allowing the worm to propagate quickly: by January 2009, the estimated number of infected computers ranged from almost 9 million to 15 million. Antivirus software vendor Panda Security reported that of the 2 million computers analyzed through ActiveScan, around 115,000 (6%) were infected with Conficker.
Recent estimates of the number of infected computers have been more notably difficult because of changes in the propagation and update strategy of recent variants of the worm.
