Aliases :

Adware.Zango.V is also known as 180Solutions, 180SearchAssistant, Zango.

Explanation :

Adware.Zango is a potentially unwanted application with adware capabilities that runs in the background, monitors user search queries and displays ads based on them. It also installs a toolbar in Internet Explorer that changes its interface and display links related to user searches.

The application comes however with an EULA (license agreement) that explicitly specifies the software’s behavior and therefore, when agreed, Zango cannot be held responsible for this software.

When installed, Adware.Zango performs the following actions:

1. Creates its install folder with one of the following names:

%program-files%ango
%program-files%Seekmo

2. Creates the following files in the install dir:

in[version nr]CoreSrv.dll
in[version nr]HostIE.dll

to the registry subkey:
