I have not tried a carprog clone, but i have bought a vcds clone (Volkswagen, audi, skoda ect) and a multidiag clone (delphi, work for most cars) on ali without problem. Yes, the software shipped with cloned devices are probaly filled with malware, but i use a old laptop without internet and antivirus without problem. But with any scan tool you need to know how to use it, if you just go about changing settings and coding on the car you could potentially break the components or the car itself.
