Trojan.DNSchanger is Malwarebytes' generic detection name for Trojansthat change a systems' DNS settings without the user's knowledge or consent.
Once the systems are infected by Trojan.DNSChanger and their DNS settings modified, systems use foreign DNS servers set up by the threat actors. Infected systems that attempt to access specific sites are redirected to sites specified by these threat actors.Domain Name System (DNS) is known as an Internet standard for the assignment of Internet Protocol (IP) addresses to domain names. Simply put, DNS interprets human-friendly host names to PC-friendly IP addresses.It is common for users to automatically use DNS servers operated by their ISPs. Users who prefer more secure, faster, and reliable DNS servers usually go with a third-party serviceas ISP-administered DNS servers can be slow and unreliable.DNS changers/hijackers are sometimes bundled with other malware, such as rootkits, for example in the old TDSS family. Fake antivirus (FakeAV) programs have also been used to spread DNS changer Trojans, as seen in Rove Digital.
Malwarebytes can detect and remove Trojan.DNSChanger without further user interaction.
