If anyone receives such files, Gmail will immediately notify them with a message stating that the message was blocked because its content presents a potential security issue. If one still wishes to send such files irrespective of their contents, they can still be shared through Google Drive as well as other storage options.
Google is trying to keep up with potential security threats for a wide array of their services and through this they urge other online service providers to step up their game in order to stay competitive, thus improving the way in which we are browsing the internet without being threatened by potential security issues which might harm us.
These issues should be taken into consideration when casually surfing the net and before opening an email which seems suspicious, double or even triple check its contents before even thinking of downloading them in the respective devices. Not only will this make sure that a user is out of any harm’s way but it will also improve the browsing experience of anyone.
