#Windows10 #WindowsDefender – How to enable Windows 10’s Block at First Sight protection in Windows Defender : Windows Defender in Windows 10 may not be the best security solution, but it will keep your system safe from threats if you don’t have a third-party anti-malware program installed. Microsoft made several improvements to it in the Anniversary Update, and as a result it’s now much more useful.
Newly introduced features, available from Build 1607, include Limited Periodic Scanning, which can intermittently scan your system and notify you of any threats (even if you are using another anti-malware program and have Windows Defender turned off), and Block at First Sight protection.
What Block at First Sight does is use heuristics, machine learning, and automated analysis to determine if a program you want to run is genuine, fake, or malicious, and checks it using Microsoft cloud protection. If it’s found to be a threat, Windows Defender will block it.
This function should be enabled by default. It may not be however, as Windows Defender gets turned off automatically when you run a third-party security product.
To check the status, go to Settings > Update & security and select Windows Defender. If you’re not using another anti-virus program, make sure Windows Defender is enabled here. Turn on Cloud-based Protection, and Automatic Sample submission.
Block at First Sight should now be running, but to check, open the Group Policy Management Console by clicking Start, typing gpedit.msc, and hitting enter.
