Then how PUP.Optional.FreeCause is able to cause additional installation, adware and affections?
PUP.Optional.FreeCause is created to support advertising platform to intercept as many traffic as possible for product promotion. With BHO, Applet, Script and ActiveX technologies, the PUP application is enabled to manipulate searches and destinations.

Besides, many programs have backdoor program and it is indispensable for PUP.Optional.FreeCause so that its author could gather collected information when accessing the PUP program and gain money by allowing other web applications to share the gathered traffic. What’s worse, once the backdoor program has been attacked by other virus, there could have many more infections destroying the target system altogether, and the BHO, Applet, Script and ActiveX technologies will be utilized maliciously to help preload vicious code without examination, manipulate DNS settings without disturbance, call explorer.exe/dllhost.dll casually and so on.
