If that would be the case a lot of people would have virusses as the content comes from the Origin servers.
As we haven't heard anything, I think it's safe to say you can download them without getting a virus.
@Phantomlover1717 is right. I've been playing and downloading EA/Origin games since Early 2000, that's almost 17 years. I have NEVER gotten any kind of virus, malware or anything bad on my computer from EA Games/Origin. I trust them and, have Origin and, all of my games that need online access set to ALLOW (as exceptions to all traffic control rules) in my firewall and anti virus. I've had it that way for years, on several computers, never a problem from anything EA/Origin.
