HOW TO REMOVE SALITY VIRUS FROM YOUR PC-SALITY KILLER .

  Sality is the classification for a family of malicous software (malware), which infects files on Microsoft Windows systems. Sality was first discovered in 2003 and has advanced over the years to become a dynamic, enduring and full-featured form of malicious code. Systems infected with Sality may communicate over a peer-to-peer (P2P) network for the purpose of relaying spam, proxying of communications, exfiltrating sensitive data, compromising web servers and/or coordinating distributed computing tasks for the purpose of processing intensive tasks (e.g. password cracking). Because of its continued development and capabilities, Sality is considered to be one of the more complex and formidable forms of malware to date.

Sality killer is a  tool by Kaspersky.

DNS Virus could black out nearly 250,000 PCs on Monday

DNS-VIRUS-MONDAY:Virus could black out nearly 250,000 PCs on Monday

Reuters / By Jim FinkleBOSTON Jul 08, 2012, 21:12 IST

About a quarter-million computer users around the world are at risk of losing Internet access on Monday because of malicious software at the heart of a hacking scam that U.S. authorities shut down last November.
Some blogs and news reports hyped the risk of an outage, warning of a potential "blackout" and describing the Alureon malware as the "Internet Doomsday" virus.

Yet experts said only a tiny fraction of computer users were at risk, and Internet providers would be on call to quickly restore service. They said they considered the threat to be small compared with more-prevalent viruses such as Zeus and SpyEye, which infect millions of PCs and are used to commit financial fraud.As of this week, about 245,000 computers worldwide were still infected by Alureon and its brethren, according to security firm Deteque. That included 45,355 computers in the United States.
The viruses were designed to redirect Internet traffic through rogue DNS servers controlled by criminals, according to the FBI. DNS servers are computer switchboards that direct Web traffic.
When authorities took down the rogue servers, a federal judge in New York ordered that temporary servers be kept in place while the victims' machines were repaired. The temporary servers will shut down at 12:01 a.m. EDT (0401 GMT) on Monday, which means the infected PCs that have not been fixed will no longer be able to connect to the Internet.
Some U.S. Internet providers, including AT&T Inc and Time Warner Cable , have made temporary arrangements so that their customers will be able to access the Internet using the address of the rogue DNS servers.
Information on how to identify and clean up infections can be found on a website that a group of security firms and other experts set up: http://www.dcwg.org.
"It's a very easy one to fix," said Gunter Ollmann, vice president of research for security company Damballa. "There are plenty of tools available."
Many of the machines that remain infected are probably not in active use since most victims were notified of the problem, said security expert Johannes Ullrich, who runs the Internet Storm Center, which monitors Web threats.
The United States has charged seven people for orchestrating the worldwide Internet fraud. Six were arrested in Estonia, while the seventh, who was living in Russia, is still at large. Tallinn has so far extradited two of the men to New York where they appeared in Manhattan federal court.
