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 affects productivity, preventing tasks from being carried out:

  • In the affected computer: it displays pop-up windows.
  • In the local network: it carries out denial of service attacks against web servers or databases on the local network.

 

It reduces the security level of the computer: it changes the security settings of Internet Explorer, decreasing its security level.

 

It uses stealth techniques to avoid being detected by the user:

  • It injects itself in running processes.

 

It uses several methods in order to avoid detection by antivirus companies:

  • Its code is encrypted and it is only decrypted when it is going to run. Because of this, its code is not legible through a memory dump.

 

GoogleError 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.

 

Visible Symptoms

 

GoogleError is easy to recognize, as it shows the following symptoms:

  • It changes the homepage of Internet Explorer.
