CyberDefender Scam

Okay, first of all, i downloaded cyber defender one day and it told me that my cpu has 400 viruses (obviously it didn't) when i checked the infected files, most of the files were legitimate. When i decided to uninstall cyberdefender, my cpu got flooded with viruses because it directs you to one of cyberdefender's pages. Now what i'm curious is that how can the FCC allow cyberdefender to advertise radio messages about their product even though it gives ur cpu viruses and it charges you to get your cpu cleaned? Anyone knows?
