Hello. My mothers friend fixed our computer and i am wondering some things about it so if you could answer these questions and this siutation id be greatful. So today my mother got her friend to fix our computer. She told me that he already had the windows OP system at his house so he could put it on the computer after he fixed it. Now my question on this. Is it possible to give us a windows OP system without doing something illegal? She also told me he was putting a virus protecter on it. Now my question for this is can you have a virus protecter without paying for it? He put some songs on the computer aswell (i think music sharing is illegal not sure) So if you could answer these it would help me out or if i you could give me any tips on what to look for if theres any way to tell if these things are illegal. I should tell you that my mother is fine with this and she didn't pay him to fix it or anything.
