Brief Description 

    

Adware refers to programs that display advertising using any means: pop-ups, banners, changes to the browser home page or search page, etc. The advertisements could be associated with the products or services offered by the creator of the program or by third-parties.

Adware can be installed in a number of ways, on some occasions without users' consent, and either with or without users' knowledge of its function.

 

It captures certain information entered or saved by the user, with the corresponding threat to privacy: user's browsing habits.

 

It affects productivity, preventing tasks from being carried out:

  • In the affected computer: it displays pop-up windows.

 

It reduces the security level of the computer: it opens one or more ports to allow remote access to the computer and takes action that compromises user confidentiality.

 

WinButler does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
