Trojan:Win32/Popureb.E is a malicious program that is unable to spread of its own accord. It may perform a number of actions of an attacker's choice on an affected computer.

Trojan:Win32/Popureb.A is a trojan that modifies the hard disk's MBR (Master Boot Record). It changes Internet Explorer's start page and also displays unwanted advertisements.

Trojan:Win32/Popureb.B is a trojan that displays advertisements, and modifies the affected user's Internet Explorer start page.

Trojan:DOS/Popureb.A is a detection for a malformed MBR (Master Boot Record) generated by Trojan:Win32/Popureb.A. It loads the encrypted malicious code and stores it as disk sectors when the affected computer boots.

VirTool:WinNT/Popureb.A is a component of Win32/Popureb. It uses a low level disk driver hook to prevent a malicious Master Boot Record (MBR) and other malicious data stored as disk sectors from being changed.

Trojan:Win32/Apropos.B is a Trojan that may be installed by Trojan dropper Trojan:Win32/Apropos.B.dr on computers running Microsoft Windows. The Trojan dropper also installs rootkit VirTool:WinNT/Zufyx.A, which hides Trojan:Win32/Apropos.B. Trojan:Win32/Apropos.B connects to certain servers from the infected computer to receive commands from attackers.   

Trojan:Win32/Alureon.gen!B is generic detection for 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.gen!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/Agent.B is a Trojan that redirects Web traffic and manipulates certain Windows applications. Trojan:Win32/Agent.B may install other unwanted software, or may be bundled with other unwanted software.

Trojan:Win32/Tibs.DV is a Trojan that allows unauthorized access to an infected computer. The Trojan receives commands indirectly from a remote attacker via its connection to a malicious peer-to-peer network. This Trojan also contains advanced stealth functionality that allows it to hide particular files, folders and processes.
