AdPartner is a spyware.
Spyware programs are usually included in free applications downloaded from the Internet.
These programs are installed on the affected computer, sometimes without user consent, without warning users that these programs will collect user de-tails, such as Internet usage, pages viewed, phone connection details, inventory of the applications installed in the computer, etc.
Then, this information will be sent to Internet advertising companies, without the user's consent and without users realizing.
Additionally, AdPartner registers itself as LSP (Layered Service Provider), in order to harvest users' information about their connection, such as Internet usage, pages viewed, phone connection details, inventory of the applications installed in the computer, etc.
LSP (Layered Service Provider) is a Windows feature that allows to specify a number of programs, in order to process all the TCP/IP traffic taking place between Internet and the applications that are accessing Internet (such as the web browser, the email client, etc.).
For example, it could be specified a computer security program, which analyses the traffic in search for viruses or other threats before transferring it to the final application of the traffic.
However, this structure can also be used by adware and spyware programs, in order to intercept the communication across the Internet, and, what is worse, if they are deleted without taking precautions, the Internet connection will stop working indefinitely.
