Do I need an antivirus on Windows 10 Windows 11 and is the built-in defender reliable

It's been a long time since computer owners realized that their device needed protection. After all, visiting a suspicious site can lead to the appearance of a non–disappearing banner on the screen, and installing an unverified program can lead to the theft of personal data. Today, such problems are less common, and therefore the question of whether an antivirus is needed on the Windows 10 Windows 11 operating system is raised again. Further in the material you will find an exhaustive answer.

Is Windows Defender reliable

Probably, no one needs to explain that the vast majority of antiviruses are paid. For a long time, users were forced to buy a license for a year or another period for their own money to protect their computer. But Windows 10 has a built-in defender that does not require a penny from the owner of the computer. But is such a method of fighting viruses really reliable?

Firstly, you should not mistakenly believe that you are not paying for the use of a standard defender. Its price is already included in the price of licensed Windows 10, and the operating system itself can be preinstalled on a computer with an appropriate markup. Be that as it may, it says nothing about the level of security with Windows Defender on board. An overview of the functions and features of the defender will be much more informative.

For the record. Sometimes the built-in defender makes mistakes by blocking secure files and applications. However, antiviruses of other developers are not without a similar problem.

A standard means of protection, by analogy with paid antiviruses, can monitor hazards in real time or perform a full check of the device at the user's request. If we talk about specific figures, then it is worth referring to the study based on the AV-Test test. It shows that the pre-installed defender recognizes 99.8% of common threats, that is, the risk of infection of the computer is minimal, and Windows Defender can be used as a replacement for a paid analogue.

Unfortunately, the Internet has not become safer over time. On the contrary, attackers are finding new and new ways to infect ordinary people's computers. However, there is protection not only in Windows 10, but also in any browser that you use, be it Edge, Chrome or Yandex.

However, the security system of the web browser will not protect you from downloading and installing software that can interfere with the operation of the device. It will not be possible to do without Windows Defender here. Only he or a third-party antivirus can protect your privacy.

If Windows Defender is so reliable, then you don't need to install a third-party program? In general, this question can be answered in the affirmative. However, the standard Microsoft defender has a flaw regarding the detection of zero-level attacks. In this regard, the indicator of the built-in tool is only 88%, which should be called a bad result.

For example, one of the most popular Avast antiviruses recognizes 98.8% of hidden threats. And Kaspersky Internet Security shows itself better than others, which is gaining 100%, both in detecting common threats and in preventing hidden attacks. Another thing is that an ordinary user who does not visit suspicious sites and installs applications only from trusted sources will not notice the difference. Therefore, let everyone determine the need to purchase a third-party antivirus license for himself.
