Years ago, keeping your Mac malware free was a very simple task. Cybercriminals simply didn’t have much interest in infecting Macs due to their smaller user base so they didn’t put the effort into developing Mac malware. Times have changed, of course. These days there are numerous threats that target users of Apple’s desktops and laptops.

A good number of those threats are delivered via compromised web pages and so-called malvertising. That’s why a change Google will deliver later this month to Chrome users who use Macs is so important. As March finishes going out like a lamb, they’ll be introducing Mac-specific improvements to their Safe Browsing protection.

According to Google’s transparency report, Safe Browsing currently protects more than a billion people. Google discovers thousands of new malicious websites every day and protects millions of users across multiple operating systems from falling into their traps on a weekly basis.

To make things even safer for their Mac users, Google will focus on two key malicious behaviors: ad injection and settings changes. These are tricks that shady software will employ to shove unwanted (and often unexpected) ads in your face or hijack your searches, usually in an attempt to make a quick buck off their victims.

If you happen to encounter a site that’s been caught attempting this sort of thing, Chrome will throw the breaks on your browsing and display the large, ominous warning you see above. And because security by default is security that works, the only button you see will take you back to the previous page you were browsing.
