# Industry antivirus tests
|
||
|
||
Microsoft security stack continually performs well on independent tests.
|
||
|
||
## Top scoring in independent tests
|
||
|
||
Microsoft has worked hard to make our capabilities increasingly more effective by utilizing heuristic detections, machine learning, behavioral analysis, and other evolutions. That is why [Windows Defender Antivirus is the most deployed in the enterprise](https://docs.microsoft.com/windows/threat-protection/windows-defender-antivirus/windows-defender-antivirus-in-windows-10).
|
||
|
||
The time and effort Microsoft puts into improving Windows Defender Antivirus continues to show in the form of consistently high scores from independent tests.
|
||
|
||
## AV-TEST
|
||
|
||
AV-TEST is an independent IT security institute from Germany and has been testing internationally relevant IT security products for over 15 years.
|
||
|
||
The AV-TEST Product Review and Certification Report tests on three categories: protection, performance, and usability. The scores listed below are for the protection category against malware infections which has two scores, the AV-Test reference set (known as just "prevent malware") and the real world testing.
|
||
|
||
**Prevent malware** refers to detection of widespread and prevalent malware discovered in the last 4 weeks.
|
||
|
||
**Real-world testing** refers to protection against 0-day malware attacks, inclusive of web and e-mail threats.
|
||
|
||
||**January-February 2018** | **March-April 2018** |**May-June 2018**|
|
||
|-----|-----|-----|-----|
|
||
|Prevent Malware detection rate:| 99.92%, 100.00%|100.00%, 100.00%|100.00%, 100.00%|
|
||
|Real World detection rate:| 100.00%, 100.00%| 98.00%, 100.00%| 100.00%, 100.00%|

### Graphs

## AV Comparatives
|
||
|
||
AV-Comparatives is an independent organization offering systematic testing for security software such as PC/Mac-based antivirus products and mobile security solutions.
|
||
|
||
The results show the AV Comparatives Enterprise Real-World Protection Test
|
||
|

### **March-June 2018**
|
||
|

|
||
## Factors not represented in the tests
|
||
|
||
It is important to remember that [Windows Defender ATP](https://www.microsoft.com/en-us/WindowsForBusiness/windows-atp?ocid=cx-blog-mmpc) (which integrates our antivirus capabilities and the whole Windows security stack) provides a much larger set of protection features that are not factored into the tests. These features provide **additional layers of protection** that help prevent malware from getting onto devices in the first place.
|
||
|
||
To see these capabilities for yourself sign up for a [90-day trial of Windows Defender ATP](https://www.microsoft.com/windowsforbusiness/windows-atp?ocid=cx-blog-mmpc) today, or [enable Preview features on existing tenants](https://docs.microsoft.com/windows/security/threat-protection/windows-defender-atp/preview-settings-windows-defender-advanced-threat-protection).
