Clicking anywhere on the download page eventually drops an "update.hta" file on the victim's system, which if opened, downloads the master PBot installer from a remote command-and-control server.

PBot consists of "several Python scripts executed inwards sequence. In the latest versions of the program, they are obfuscated using Pyminifier," the researchers say.
If PBot finds whatever targeted spider web browsers (Chrome/Opera) installed on the victim's system, it uses "brplugin.py" script to generate DLL file as well as thence injects it into the launched browser as well as install the advertizing extension.
