The ad Turbo your PC is malware. I downloaded the exe file and installed it to find there is a demand for payment at the last step before the cleanup is effected. I immediately deleted the exe file and uninstalled the program to find that my home page of Mozilla Firefox had been hijacked and replaced by the Yahoo homepage. I have nothing against the Yahoo homepage but I want the Mozilla Firefox homepage to remain as it now is - after I restored it. I will warn all users about this Turbo scam.
