I just eliminated a bunch of malware, viruses and adware I did not okay. My computer would barely function. I was able to spot the source of at least one positively, the Frogger download through the survey page. I suspect these downloads for credit are the source of most of the rest of it. So please beware. Malwarebytes, Spybot and Security Essentials missed all of it. I lucked out and ran a free program, Avast, which did a tremendous job of cleaning my computer.
