Trojan:Win32/Alureon.BP is a detection for a particular Microsoft Windows DLL file that has been modified to load a malicious library.

 

A file detected as Trojan:Win32/Alureon.BP is a modified MSVCRT.DLL file. This file may have been modified by another malware. The modification replaces an API (Application Programming Interface) exported by MSVCRT.DLL with a snippet of malicious code designed to load a DLL named DLL.DLL, which is possibly a dropped malicious component of the Win32/Alureon family of trojans.

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.

Virus:Win32/Alureon.G is a detection for system drivers infected by members of the Win32/Alureon family.
