Where can I get a safe (no virus, malware, etc.) free download of The Sims Deluxe Edition?

I got The Sims Deluxe Edition and a few expansion packs from a library event. The problem is, one of the CDs for downloading it is missing. So I'm looking for a free (since I already got it the first time) and safe (without harmful computer software) version online that I could download. Thanks!
