Yes, there are several good DS emulators available.

I've been using it for years without encountering any viruses or issues.
For ROMs I download from emuparadise, though for emulators I always choose the official developer site because it stays more current than emuparadise. With GameboyAdvance I use VBA-M. In my opinion, it’s quite handy—it lets you link and trade Pokémon easily, and you can save snapshots to load them on an Android phone. You can also copy the saved file directly from the game. Still, I favor snapshot backups for safety.
