Upon consideration, I'd consider the existence of viruses/malware for a platform is actually a good thing, as it's a sign of openness. If there isn't, it's most likely because there is a central authority deciding what you can and cannot do on the platform.

And if someone else controls what you can and cannot do on the platform, the platform really isn't secure from your point of view. This is especially true when that someone not only has that control but also has access to your activities, metadata, data, PII, etc through cloud based applications and features, telemetry, central store registration/purchases, etc.
