You should think what malware is. Maybe apple software is malware as well. Anyways if you could review the source code of the "malware" you (or people who can read it)could know what it does in advance and avoid it. And code could be signed and verified and still be free software. Linux distros verify software signatures and have almost no malware problems and at the same time use a lot of free software. So free software makes users more secure if anything.
