Defender focuses more on reducing its system impact than ramping up scan times. But does this work? It’s unclear. PassMark’s AntiVirus Performance Benchmarks says otherwise, though, with Defender ranked 4th best out of 12 for its minimal performance impact. Meanwhile, AV-Test’s Windows Consumer performance results are somewhere in the middle; sometimes Microsoft Defender scores well, but not always, and it’s not as consistent as many top antivirus apps.
Protection is what really matters with any antivirus, and Microsoft Defender’s rating, like just about everything else about the package, is mixed. Still, Defender wasn’t far behind Bitdefender For example, one group of tests involves using trusted Windows apps to download malicious files, a common scripting trick.
Bitdefender and Kaspersky realized there was a problem purely from the behavior, and killed the process before it could download the file. Microsoft Defender accepted the behavior, allowed the download, and only raised the alarm when it realized the file was malicious. It still protected us, this time, but perhaps wouldn’t have done if the threat were brand new. We pitted Microsoft Defender against our custom ransomware, but it missed that, too, allowing it to encrypt thousands of test files.
Turn this on and it automatically blocks unauthorized apps from accessing key document folders Documents, Pictures, Videos, Music, more and you can easily add more. We turned Controlled Folders on, added our test folder to the list, and ran the ransomware simulator again. This time, Defender displayed an alert when our ransomware tried to access the folder, and it wasn’t able to encrypt any documents. This isn’t exactly sophisticated. Controlled Folders simply blocks everything it doesn’t recognize, and we found a couple of legitimate programs refused to run until we’d manually added them to an Exceptions list.
Avast’s Ransomware Shield is smarter, more like a firewall; when it detects an unauthorized access to a folder, it alerts you, but also asks if the process is legitimate. Confirm it, Ransomware Shield adds the app to your Exceptions list itself and there’s nothing else to do. Controlled Folders could be better, then, but it did its core job, keeping us safe from a threat that the antivirus engine missed.
We’re not going to discuss it in depth here, but Windows’ OneDrive integration helps a little, too. The standard 5GB of free online storage space isn’t a lot, but it’s free, it’s 5GB more than you’ll get with most security apps, and it could help you protect some of your most important data from attack.
Top of the list is probably the firewall. This does a fair job of protecting you from incoming network attacks, but it’s less interested in controlling outbound access; if an app is able to run as an administrator, it’s able to customize the firewall by adding its own rules. Any system firewall has to do that, but it does allow many apps to leave a mess behind as they add rules, then ‘forget’ to remove them when uninstalled.
Don’t start deleting anything unless you’re sure what you’re doing and have a backup available, though; it’s easy to make a mistake. Defender’s reputation-based SmartScreen protection allows it to block access to malicious websites, files and apps. Its URL filtering is consistently less accurate than the competition in our tests, and, worse, it only works with Microsoft Edge.
SmartScreen’s file and download checks work system-wide, though, and they’re a useful extra layer of protection.
