2016 Microsoft released Windows Defender Advanced Threat Protection



Windows already ships with built-in antivirus called Windows Defender. Currently, it’s a defensive program that looks at websites and downloads to try and stop you from getting hacked. Unfortunately, in the day and age of social engineering and spear-phishing, antivirus needs to be a little more proactive. The new cloud service Windows Defender Advanced Threat Protection is supposed to be that protection for large, company-wide networks. WDATP move the focus from monitoring individual files to the machine’s behaviour as a whole—rather than searching for the actual virus, it keeps an eye on symptoms. If your machine starts connecting to weird ports or executing unusual PowerShell commands—behavior that’s out of the ordinary for the vast majority of users—WDAPT will flag it to administrators, providing an overview of current and past behavior for admins to look at. Microsoft’s also trying to take advantage of the vast Windows install base to kickstart its antivirus program. Millions of suspicious files found on machines worldwide will be run on the cloud, building a giant centralized database of malicious files, but also malicious behavior.
