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.

Virus Characteristics
This detection covers scripts in which malicious iFrame(s) is appended to the end of a HTML page, i.e. after the < /HTML > tag.
The recent variant also included Javascript obfuscated malicious iFrames. These iFrames will lead to redirection of the browser window to browser exploits that will download and execute malware on user's computer.
