1. The question is also applicable to ‘free down loaded’ soft wares (If these are infected by viruses, Mal wares and Trojans).
2. I am not saying that all such softwares are infected. What I am saying is that, in case they are infected, can they(pirated and free-down loaded ones) be cleaned by anti-virus software.


Only if you use pirated Anti-Virus Software.
It depends on the quality of the antivirus/malaware etc software. Some are better than others. Theoretically yes.
its depends on anti virus
also you are using paid or free anti virus
and its is updated or not
I’m sorry but I don’t know
