What is cosstminn?

This adware program is a JustPlug.It web browser extension that is delivered via the WebPick (InstalleRex) download and install manager. It is included with various adware offer bundles and is a cross browser extension that runs with multiple parts including a Windows service, an auto-starting component and the browser toolbar/plugin which is designed to inject advertisements in the browser in form of banner ads, hyper-text links and popups. In addition, some versions might hijack existing advertising on web sites as well as inject affiliate codes in links as coupon offers. The program will install itself in a folder with a random name in Program Files or ProgramData and each of the included files will also have a shared random generated name. The advertisements that are displayed in the browser could include deceptive malvertising ads for 'required' updates of known common programs as well as unwanted pop-ups advertisements. If downloaded these programs install a number of bundled adware utilities and additional browser extensions. Additionally components of the program will modify the browser's default security levels.
