No, you don't see Avast or AVG, etc, antivirus bundled inside an ImgBurn installer, or anything like that. At least I've never seen that. Making people install an antivirus just as if it were nothing on the system is potentially dangerous, especially because people may already have one installed, so that's two already, and then maybe you already got Baidu without asking for it, then you get PSafe too, and what if that is the third AV in your system? You see my point?
Antiviruses are supposed to rid the user of unwanted and malicious programs, not to be a nuisance themselves. But that's just my opinion.
