Microsoft's Edge browser uses a virtual machine to quarantine itself from malware

Intent on winning over more of the enterprise browser market, Microsoft has unveiled a new security feature it’s calling “Windows Defender Application Guard.” It’s a mouthful, but it will reportedly make Edge one of the most secure browsers available. The feature uses a “mini virtual PC” to isolate Edge from the rest of your system, effectively quarantining the entire browser to prevent malware from gaining access to sensitive files.

“Even if an untrusted site successfully loads malware, the malware is unable to reach beyond the isolated container to steal data or permanently compromise devices or the network,” Microsoft wrote in a blog post detailing the new security features.

Unfortunately, this new ironclad version of Edge isn’t available to most consumers. Engadget reports that it’s currently limited to Windows 10 Enterprise, where system administrators will be able to determine which sites will be run inside the secure virtual machine version of Edge.

“Once enabled, enterprise administrators can configure a trusted network site list policy and distribute the group policy to any devices it wishes to protect with the Application Guard,” Microsoft’s blog post continues.

Running Edge in a virtual machine will reportedly take a toll on your performance, slowing things down when you’re running a particular website in the secure environment. Keeping Edge securely segregated from the rest of your system uses a fair amount of resources, but Microsoft stated in its blog post that the Application Guard has been optimized to run as light as possible.

The Application Guard will be available to Windows Insiders running Windows 10 Enterprise in the next few months, and, according to Microsoft, it will be rolled out more broadly next year. So, it’s going to be a while before you’ll be able use the Application Guard on your home install of Windows 10, but given the prevalence of malware these days, it should be worth the wait.

Hackers are using this incredibly sneaky trick to hide malware

One of the most important things you can do to protect your online security is install one of the best password managers, but a recent cyberattack proves that you have to be careful even when doing that. Thanks to some sneaky malware hidden in Google Ads, you could end up with viruses riddling your PC.

The issue affects popular password manager KeePass -- or rather, it attempts to impersonate KeePass by using misleading Google Ads. First spotted by Malwarebytes, the nefarious link appears at the top of search results, meaning you’ll likely see it before the legitimate websites that follow beneath it.

Microsoft has just taken a vital step towards better protecting your devices from malware, and it’s one that could stop viruses dead in their tracks. Interestingly, though, the Redmond giant seems to have made no mention of the change, despite its significance.

The new policy might sound minor on the surface: Microsoft’s SharePoint cloud storage service can apparently now scan files that are encrypted or password-protected. Previously, this wasn’t thought to be possible.
