Bitcoin miners are good folk, by and large. That's why it's always disheartening when we hear about a case of Bitcoin thieving and scheming. An investigation by Malwarebytes last week found that a company named Mutual Public a.k.a. We Build Toolbars a.k.a. Your Free Proxy has been installing Bitcoin mining software on unwitting users' computers through unrelated downloadable toolbars and a proxy service (and possibly other products.) The software operates in the background, bogging down the computer's CPU and mining Bitcoin for the sole profit of Mutual Public. It legitimizes the practice by explaining its activities in the nobody-ever-reads-them EULA for the installed toolbars. And the software is difficult to permanently delete.
