I don’t know of anyone getting an actual computer virus from the exchange BUT EA has very little control over what people upload to the exchange. The Exchange: Use caution when downloading from the exchange. None of that can give you a virus, period.
Sims 2, Sims 3, Expansions, Stuff packs, downloadable content from the store. Purchased Sims Games and EA Store Downloadable Content: Nothing EA Games makes is going to give you a virus. Torrent Downloads: If you try to torrent any game (ie: download it for free) there is a much higher chance of you getting a virus that way than any other way, in The Sims. So I thought I would write a little explanation about sims, viruses and my experiences. I have had a number of people ask me about downloading custom content and viruses.
