Overview

This is a trojan detection. Unlike viruses, trojans do not self-replicate. They are spread manually, often under the premise that they are beneficial or wanted. The most common installation methods involve system or security exploitation, and unsuspecting users manually executing unknown programs. Distribution channels include email, malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer networks, etc.

Aliases

• BackDoor.Pyand (DrWeb)

• Trojan.Win32.StartPage.b (AVP)

This Trojan is compressed with the UPX packer. When run, it will modify the Internet Explorer start page setting. This is accomplished by changing a setting in the registry.
