For the most part, it’s perfectly safe to download mods and CCs. Creators likely don’t put viruses or malware into the downloads. They make their mods and CCs because they love the game and have a passion for expanding everything you can do on The Sims 4. The only thing to worry about is if the website is infected with viruses or malware. Because of this, you should still exercise caution when downloading Sims 4 mods and CCs.
