There are millions of pirate so you can assume this doesn't happen to most people. If the expected return on piracy was negative people would not pirate. With trusted uploaders you can also reduce the risk further because if they release malware their reputation will be ruined. That's not even taking into account the fact that people already run non-pirate executable code without auditing it from basically anywhere so the risk is about even I'd think.
