Windows Update for Conficker-C Virus

How to remove Conficker C worm


Malware Description:
Conficker C (aka W32/Conficker.C or Conficker.C) is a predictable successor of Conficker B++ worm which has been spreading more than rapidly throughout the planet. Most of the legitimate antivirus programs have given Conficker.C a high severity scale so this worm should be kept away from at all costs. Conficker C worm does not apparently manifest itself on the compromised computer, so it’s critical to have trusted antivirus software installed and scan the machine for malware at regular intervals. The basic hidden impact Conficker C produces on the infected computer is disabling the use of security software, thus creating itself a favourable environment for affecting more operating system processes. Conficker C worm is also known to have blocked the option of following URLs of web resources providing PC security services. The above malfunctions are called forth by Conficker C modifying firewall configuration and dropping corrupt files and registry entries on the contaminated machine. With Conficker C worm on board, you will not be able to update your antivirus software, therefore your system will be under a potential risk of an overwhelming malware invasion. In addition to the above, Conficker C is capable of performing latent actions aiming to steal the victim’s persona data and send it to remote attackers. If you have noticed any probable signs of Conficker.C presence in your system, e.g. not being able to visit some sites you used to visit, make sure you run a security scan to detect the worm, and remove it once spotted to keep your PC safe.

Conficker C True Or False April 1st


just to inform everyone.....i dont know if its true....

In an event that hits the computer world only once every few years, security experts are racing against time to mitigate the impact of a bit of malware which is set to wreak havoc on a hard-coded date. As is often the case, that date is April 1.

Malware creators love to target April Fool's Day with their wares, and the latest worm, called Conficker C, could be one of the most damaging attacks we've seen in years.

Conficker first bubbled up in late 2008 and began making headlines in January as known infections topped 9 million computers. Now in its third variant, Conficker C, the worm has grown incredibly complicated, powerful, and virulent... though no one is quite sure exactly what it will do when D-Day arrives.

Thanks in part to a quarter-million-dollar bounty on the head of the writer of the worm, offered by Microsoft, security researchers are aggressively digging into the worm's code as they attempt to engineer a cure or find the writer before the deadline. What's known so far is that on April 1, all infected computers will come under the control of a master machine located somewhere across the web, at which point anything's possible. Will the zombie machines become denial of service attack pawns, steal personal information, wipe hard drives, or simply manifest more traditional malware pop-ups and extortion-like come-ons designed to sell you phony security software? No one knows.

Conficker is clever in the way it hides its tracks because it uses an enormous number of URLs to communicate with HQ. The first version of Conficker used just 250 addresses each day -- which security researchers and ICANN simply bought and/or disabled -- but Conficker C will up the ante to 50,000 addresses a day when it goes active, a number which simply can't be tracked and disabled by hand.

At this point, you should be extra vigilant about protecting your PC: Patch Windows completely through Windows Update and update your anti-malware software as well. Make sure your antivirus software is actually running too, as Conficker may have disabled it.

Microsoft also offers a free online safety scan here(Windows Live OneCare safety scanner: Free online tool for PC health and safety), which should be able to detect all Conficker versions.
