An antivirus does not work the same as any other simple program. These security programs are executed at a very low level in order to guarantee maximum protection, and therefore they have to be designed to the millimeter so that there are no errors or possible security breaches. Any low-level changes to the operating system can cause antivirus to stop working. And more when the change is due to a completely new operating system, no matter how much Windows 11 is based on Windows 10.
Be careful when installing an antivirus in Windows 11
The security firm AV-Comparatives has tested the main antivirus on the market to see if they are capable of working on Windows 11. For this, they have used one of the latest builds available, 22454.1000, and the same tests that are carried out on these antivirus have been carried out in any other operating system to guarantee its correct operation.
The antivirus that AV-Comparatives has analyzed are:
- Avast Free Antivirus 21.7.2481
- AVG Free Antivirus 21.8.3202
- Avira Antivirus Pro 18.104.22.16811
- Bitdefender Internet Security 22.214.171.124
- ESET Internet Security 126.96.36.199
- G Data Total Security 188.8.131.526
- K7 Total Security 16.0.0556
- Kaspersky Internet Security 184.108.40.2061
- Malwarebytes Premium 4.4.6
- McAfee Total Protection 16.0
- Norton LifeLock Norton 360 220.127.116.11
- Panda Free Antivirus 21.00.00
- Total AV Total Security 5.15.69
- Total Defense Essential Antivirus 18.104.22.1685
- Trend Micro Internet Security 17.0.1181
- VIPRE Advanced Security 22.214.171.124
Although all these antivirus can be installed in Windows 11 without problems, activate the shields and even integrate within Windows Security, as of September 28, 2021, none of the above antiviruses officially support the new operating system. Just go to the website of any of the antivirus that we have just seen and see how its developers have not yet added Windows 11 to the list of supported operating systems.
What does this mean? That these security programs do not guarantee correct operation in the company’s new operating system. And, although we can install them, they work without problems and nothing may happen, since an antivirus is such a complex program it is easy for something to fail, end up going wrong and expose our computer to the dangers that plague the Internet. And, if a problem occurs, the company is not responsible.
Therefore, in the absence of a week for the Windows 11 official release, only an antivirus certifies its operation in this new operating system. And this is none other than …
Windows Defender: the best option
Things have changed a lot since Microsoft started flirting with its own antivirus, a security suite called “Security Essentials,” which was literally useless. Since Windows 8, Microsoft has gotten the hang of it when it comes to security, and with Windows Defender Not only does it offer a security solution to match a system with millions of users worldwide, it is even ahead of many other commercial suites.
Of course, Windows 11 comes with a new version of this antivirus to protect users from all threats that may appear on the network. In addition to viruses, Windows Defender will protect us from ransomware and other threats, it will continue to be a totally free antivirus for all users, it will come installed as standard and, thanks to it, we will be able to navigate with peace of mind with the certainty that no threat will end up taking control of our PC.
Everything looks very nice, but what is your problem? Windows Defender sins a bit of consuming too many resources when installing new programs on the PC. Leaving this aside, we are facing an antivirus of 10. And best of all, today, the only certificate for Windows 11.
