What Is Trojan Puper?

This section provides a quick description of what is trojan and malware 'Puper' infecting Internet Explorer on Windows systems.

Puper is a malicious program for Windows system. Here are some short descriptions of Puper I found on the Internet:

1. From www.spynomore.com/trojan-search-hijacker-puper-updatesearches.htm

Alias of Puper are Puper.UpdateSearches and Trojan.Puper

Puper.UpdateSearches is a trojan malware application that changes 
Internet Explorer's default home page and default search URL and 
redirects traffic to updatesearches.com website. Puper.UpdateSearches
displays the a pop-up window with false spyware warning.

2. From vil.nai.com/vil/content/v_133666.htm:

The puper family of trojans are used to modify the internet explorer 
home page and search page in addition to monitoring internet usage.

The puper trojan monitors its own processes and will continually 
execute them to ensure they stay in memory.  Additionally it will 
launch every time explorer.exe gets launched.

This trojan may drop hpxxxx.tmp where xxxx is random characters.  
This file will be detected as puper.dll and is responsible for the 
start page and search page behavior.
