The new features are part of an improved secure browsing that Google launched last year. Chrome will ask the user to update to Google for further scanning when downloading malicious files. The file will be uploaded to Google Safe Browsing for further analysis. Chrome will alert you if the file is not secure.
The user can bypass this, but not doing so is good for the security of the device. Google claims that users who use enhanced secure browsing are only 35% less likely to fish than other users.
