AV-TEST ranked the suite as one of the best antivirus options for home users in February, but later tests by AV-Comparatives found no improvement, while TechPowerUp (TPU) recently found Defender is hogging resources on Intel machines.

“The Advanced Threat Protection tests provide vendors and users with substantial findings as to how securely a product can protect against ransomware in real-life scenarios.

The manufacturers of the products for consumer users are: Avast, AVG, Bitdefender, F-Secure, G DATA, K7 Computing, Kaspersky, Microsoft, Microworld, NortonLifeLock, PC Matic and VIPRE Security.

[…]The solutions tested for business users are products from the following vendors: Acronis, Avast, Bitdefender (two versions), Comodo, F-Secure, G DATA, Kaspersky (two versions), Microsoft, Seqrite, Symantec, Trellix and VMware.

All the products have to successfully defend against ransomware in 10 real-life scenarios under Windows 10. The test involves threats such as files containing hidden malware in archives, PowerPoint files with scripts or HTML files with malicious content.”


Microsoft Defender consistently performed amongst the top solutions in both personal and business categories. The suite was able to detect ransomware attacks early, which is important for alerting customers and giving them time to act to precent threats.

In home use, Defender detected all but one infection, while in enterprise Defender was able to detect all 10 infection tests.
