Who do you think downloads and runs malware? Users.

By the same argument we should prevents the users from running any program at all because it might be malware.

That is indeed what many people want! Look at people defending "app stores" as being for the users' own good, and sometimes everyone else's.

No, but we shouldn't treat user's freedom as an anti-virus mechanism. Pretending that user acceptance will help in preventing malwares is extremely naive.
