Status:
Adware

Explanation:
The setup file is part of the Soft32.com download and install manager. It is an ad-supported installer and attempts to get the user to install various adware toolbars, browser add-ons, game applications or other potentially unwanted programs. If a sponsored software offer such as a toolbar is installed it might change the User’s home page, default search settings and 404 traffic. Note, the software installed by Soft32 is probably safe, just the installer is unwanted.

Description:
This is also known as bundleware, or downloadware, which is an downloader designed to simply deliver ad-supported offers in the setup routine of an otherwise legitimate software.
