Trojan:Win32/Alureon.gen!W is a generic detection for a component 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.
 
The Win32/Alureon trojan 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. Therefore it may be necessary to reconfigure DNS settings after the trojan is removed from the computer.

Virus:Win32/Alureon.G is a detection for system drivers infected by members of the Win32/Alureon family.
 
Win32/Alureon is a multi-component family of trojans involved in a broad range of subversive activities online in order to generate revenue from various sources for its controllers. Mostly, Win32/Alureon is associated with moderating affected user's activities online to the attacker's benefit. As such, the various components of this family have been used for:
  • modifying affected user's search results (search hijacking)
  • redirecting affected user's browsing to sites of the attacker's choice (browser hijacking)
  • changing DNS settings in order to redirect users to sites of the attacker's choice without the affected user's knowledge
  • downloading and executing arbitrary files, including additional components and other malware
  • serving illegitimate advertising
  • installing Rogue security software
  • banner clicking
 
Win32/Alureon also utilizes advanced stealth techniques in order to hinder the detection and removal of its various components.
 
As some variants of this trojan may modify DNS settings on the host computer to enable the attacker to perform these tasks. Therefore it may be necessary to reconfigure DNS settings after the trojan is removed from the computer.

Trojan:Win32/Alureon.B is a trojan that may help an attacker intercept inbound and outbound Internet traffic from the host computer. This may allow an attacker to capture confidential information such as user names, passwords, and credit card data. The trojan may also enable an attacker to transmit malicious data to the infected computer. Trojan:Win32/Alureon.B may modify DNS settings on the host computer to enable the attacker to perform malicious tasks. Therefore it may be necessary to reconfigure DNS settings after the trojan is removed from the computer.

Trojan:Win32/Alureon.E is a trojan that modifies DNS settings on the host computer. The altered DNS settings may enable an attacker to intercept inbound and outbound Internet traffic in order to gather confidential information such as user names, passwords, and credit card data. The modified DNS settings may also enable an attacker to transmit malicious data to the infected computer. Because the trojan modifies DNS settings on the computer, it may be necessary to reconfigure those settings after the trojan is removed from the computer.
