Did you go to any illegal website or download any unknown apps?
No, But does that matter?
Yes, your smart phone can be easily infected by virus if you do that.
I see. I'd better never try.

Do you know what's wrong with my PC?

Is anti-virus software necessary for a PC?
Of course. You'd better learn something about it.
I'm afraid yes. But what about the data I stored in the computer?
Don't worry, it should have been protected automatically. And I take an anti-virus software with me. Do you want me to install it now?
Yes, please. I'll really appreciate that.
