This is not a virus or trojan. It is a direct-marketing adware application.

This kind of application generally comes bundled with another program, which usually discloses the fact that it is ad-supported.  Users agree to have the Adware installed in the license agreement, although they may not realise at first that this file was packaged with the product they installed.

The program comes with a dropper file.  When the dropper runs,  the program is copied as the following file:

c:\Program Files\Common Files\tsa\tsl.exe
The following Registry key is added to hook system startup:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
"Tsl" = "c:\Program Files\Common Files\tsa\tsl.exe"
The program connects to a specific web site.  It can further download other programs to the machine.  It might also post machine related information to the website.
