A couple days ago we encountered an interesting case involving Commwarrior.B and Palm Treo 700w smartphone. F-Secure, 02/16/06.

Troj/Danmec-G — A Trojan that can be used to route HTTP traffic through the infected host. It’s installed as “checkreg.exe” in the Windows System folder and displays the fake error message “Application can not run because vbrun64.dll not found”. (Sophos)

Troj/Cimuz-U — A password stealing Trojan that installs itself as “msnscps.dll” in the Windows System folder and registers as a Browser Helper Object. (Sophos)
