I see people get viruses from rom sites all the time. This is what you should know.
M.A.M.E: multiple arcade machine emulator
Dolphin: Gamecube and Wii Emulator
Snes9x: Super Nintendo Emulator
FCEUX: NES Emulator
VisualBoyAdvance: GBA Emulator
Project64: N64 Emulator
There are a lot more emulators, but these are really reliable and good.
When downloading a rom, the File extension should NEVER be an exe. If it is, then it definitely is malware.
Steam: itswomboy (I change my name a lot)
