Thankfully Chrome has fixed this issue. I just tried this and Chrome actually warns you about downloading DLLs and requires further user interaction to actually download DLL to the downloads folder:
All DLLs or just specific ones? I'd heard a while ago they were going to blacklist specific ones instead of just making it so a user has to purposely decide to download a file.
I'm surprised they finally did something since we've been warning people not to use Chrome because of this issue for years.
