Google has long allowed users to switch on the Enhanced Mode of Safe Browsing, a Chrome feature that warns users when they’re downloading a file that’s believed to be unsafe, either because of suspicious characteristics or because it’s in a list of known malware. Under the new changes, Google will prompt users to provide any password needed to open the file.”
