In return, the PUP would install the programs that helped it on the target machine, which would take up limited resource and badly harms the compactness and effectiveness of the PC performance, making the machine weak enough to be attacked easily by virus should there be any.

  3. Once is capitalized by virus, the JS and BHO techniques (the two are widely used in building websites) will be utilized maliciously to record in-put information and preload vicious codes into the target machine easily. Therefore, it is recommended to remove the sooner the better.

With huge traffic, would have online operators/advertisers paid it to direct traffic as asked. Besides, with JS technique, manages to get online whereabouts and that data can contribute to a more accurate decision on marketing strategy. The more hijacks, the more such data will be obtained and the more traffic it’ll get.
