The FBI is performing an operation of cleaning and elimination of the DNSChanger Trojan virus. This kind of malware infects computers, changing your DNS settings, and redirecting the user to malicious or fraudulent pages. DNS servers are used to translate the URL entered by the user in the corresponding public IP. If the query is made to a malicious DNS server, the URL will be translated with the public IP address of a website specially designed by the attacker malicious. On March 8, the FBI will proceed at the close of the malicious DNS server that configures the virus in infected computers, so that all those users with virus in execution will remain without access to the network (not have translation of URLs to public IPs).
To rectify the problem, it must be disinfected the machine, so that we ensure that the requests go to a trusted DNS server. For this purpose, an on-demand scan, can be done using an anti-malware protection with the updated signature file. Once is disinfect equipment, may set up a public DNS in the network parameters, or obtain one through DHCP. It is necessary to reapply the network configuration, either by restarting the network driver, or making any change in settings involving the re-aplicacion of it. Do not run virus, requests will be resolved now in a truthful manner, and the problem will be solved.
It is not necessary to wait for March 8 to check if your computer is infected (will be left without navigation). Any user can check if your computer is infected from the page:. Audea Seguridad de la Informacion. Jose Francisco Londinez Security Department TIC.
