AV-Comparatives reveals top-performing consumer antivirus products in latest Real-World Protection Test results from July-October 2021 

The independent security software evaluation lab AV-Comparatives has released the results of its Real-World Protection Test carried out between July and October 2021.  

The tests examine the performance of leading antivirus solutions in order to assess their capabilities in conditions experienced every day by users around the world.  

Nine vendors achieved a three star Advanced+ rating: Avast, AVG, Bitdefender, K7, Kaspersky, McAfee, Microsoft, Total Defense and VIPRE. 

“Malware poses an ever-greater threat, which means consumers need to have total confidence in the antivirus solutions that protect them against threats,” said AV-Comparatives co-founder Peter Stelzhammer. 

“The AV-Comparatives tests are uniquely rigorous and painstaking, using more test cases per product than any other testing lab”. 

 “This means our tests are accurate and reliable, providing an unparalleled examination of each solution. Congratulations to the top performers.” 

 Each piece of malware used in the test was analysed on a clean computer without antivirus software to decide if it is a suitable candidate. Once the malware is assessed, its source URL is added to a test list. 

The antivirus products used in the test are installed on individual fully patched Microsoft Windows 10 64-Bit computers, which are connected to the internet and updated each day as well as before every single test. 

Current malicious websites found in the field are used during assessment to make the tests as close to real-world conditions as possible.  

The Real-World Protection test is carried out as a collaboration between AV-Comparatives and the University of Innsbruck’s Faculty of Computer Science and Quality Engineering. It is partially funded by the Republic of Austria. 

Below are the vendors awarded a three star Advanced+ rating, two star Advanced rating or one star Standard rating.

 During the test, NortonLifeLock, Panda and Trend Micro all achieved a 100% protection rate. Avast, AVG and Kaspersky achieved a 99.9% protection rate, followed by McAfee with 99.8%. 

 AV-Comparatives also carried out false positive tests which examined wrongly blocked domains while browsing and incorrectly blocked files while downloading or installing.  

 Bitdefender, ESET, Kaspersky, Microsoft, Total Defense, VIPRE performed best in this test, with each product recording a false positive score of zero.  

As part of its ongoing Consumer Main-Test Series, AV-Comparatives released the results of its October 2021 Performance Test for consumer security solutions earlier in November. A total of 17 popular anti-malware programs were evaluated to assess the impact they have on the speed of a Windows 10 21H1 64-Bit system.

 A total of 13 products reached the highest ADVANCED+ award level in the Performance Test. These were: Avast, AVG, Avira, Bitdefender, ESET, G Data, K7, Kaspersky, McAfee, NortonLifeLock, Panda, Total AV, and VIPRE. These products all had a low impact on system performance.
