Google yesterday announced several new protections for its Gmail service, aimed at protecting users from malicious links and government-sponsored cyberespionage.

On its security blog, Google announced that beginning this week, Gmail users who click suspicious links in emails will receive full-page warnings that read: “Warning — visiting this web site may harm your computer!” Users can still click through if they choose. Google already identifies suspicious links in messages before they are clicked on.

Users will also begin receiving full-page warnings when Google suspects they are being targeted by state-sponsored cyberattackers. Until now, such warnings have been limited to a small red bar at the top of the page.

Finally, Google stated it is teaming up with Comcast, Microsoft, Yahoo! and other industry partners to draft a proposed standard for ensuring emails are delivered only through encrypted channels.
