Trojan:Win32/Alureon.FE is a trojan that installs other variants of Win32/Alureon, a family of data-stealing trojans. These trojans allow an attacker to intercept incoming and outgoing Internet traffic in order to gather confidential information such as user names, passwords, and credit card data. It may also allow an attacker to transmit malicious data to the infected computer. The trojan may modify DNS settings on the host computer to enable the attacker to perform these tasks. As a result, it may be necessary to reconfigure DNS settings after disinfection. Trojan:Win32/Alureon.FE also modifies the MBR to execute installed Alureon components.
