In order to ensure that every Windows user can use the best anti-virus software with the highest protection, the foreign security testing company AV-Test will test multiple sets of well-known anti-virus software on the market basically every once in a while. The latest reports for November and December have also been officially released recently. Most of them perform well, and three of them have outstanding scores, which are summarized below.

AV-Test releases test report on the best antivirus software for Windows 10
AV-Test’s test content has three aspects: “protection”, “efficiency” and “usability”, with a full score of 6 points. A total of 18 anti-virus software were tested this time, including the well-known Avast, Avira (Little Red Umbrella), Bitdefender, Kaspersky (Kaspersky), McAfee, Trend Micro (Trend), etc.
The picture below is the test report. You can see that the performance of all anti-virus software is very good, basically all have a score of 5 or above. Only some of the more unknown ones have the prefix 4, such as Total AV, eScan and Check Point:

Norton Security 22.19, Kaspersky Internet Security 20.0 and BullGuard Internet Security 20.0 are three anti-virus software. The protection, performance and usability of the three anti-virus software all scored 6 out of 18 points, which means that if you want to find an all-round good anti-virus software, you should choose from these three.
However, it should be noted that the full score given by AV-Test does not mean that all test results are perfect, but “close” or “higher than average.” For example, the malware attack of BullGuard Internet Security 20.0 did not reach 100% in December, but 99.4%:

We have shared this before Kaspersky Total Security This set is really useful. It not only has extremely high protection and safety, but also provides many practical functions.Kaspersky Mobile Antivirus The mobile version is great too.
In addition, Windows Defender built into Windows 10 is also very impressive this time, scoring 6 points for both protection and usability, but its performance is slightly worse, at 5.5 points. But I personally think this is quite strange. Logically speaking, since it is built-in, the performance should be the best (?):
