Use Windows antivirus correctly and protect your computer

Manually you can click on the button Search for updates. It will automatically start looking for possible new versions. However, unless there has been an error, it is something that will be done periodically.

Update Windows Defender

Configure protection

This point is very important, since a bad configuration could leave your computer unprotected. What you are going to do is configure different protection sections of Windows Defender to prevent the entry of malware. This is going to be key to always maintain security.

You have to go to Start and enter Windows Security. Once there you have to click on Antivirus and threat protection. There you will find different settings that you should always have enabled. If they are not, you simply have to check the corresponding box.

Configure Windows Defender protection

You need to make sure you have the following enabled:

  • Real-time protection
  • Cloud based protection
  • Against alterations

Turn on core isolation

A feature that is disabled by default is the core insulation. It is very useful to have it enabled for maximum protection. This is an option to provide an additional barrier against malware and other cyber attacks. What it does is isolate the processes from the operating system and the device.

To activate it you have to go to Start, enter Windows Security, click on Device Security and select Core Isolation. Click and you will see a box as shown in the image below. You simply enable this feature and it will be available from then on.

Reputation-Based Protection

We can say that a large part of computer attacks come through malicious applications. For example, a program that you download from an insecure site, software that has been modified to steal data, etc. For this reason, it is especially important to be protected against any application that you install.

This feature is also disabled by default. To enable it you have to go to the Windows Defender settings and access Application and browser control. Once there you simply have to click Activate. From then on, Microsoft antivirus will protect against potentially unwanted applications, files, and web pages.

Reputation-Based Protection

Activate Windows Firewall

Microsoft Defender is not just a conventional antivirus and one of the reasons is because it also has a integrated firewall. This is very useful to protect the system from unwanted access through the network. It can help prevent computer attacks, allows you to block applications from accessing the Internet, etc.

To activate it you have to go to the Windows Defender settings and this time you enter Firewall and network protection. You will see three options: domain network, private network, and public network. It is interesting that the firewall is activated in all of them. You can click on each of them and activate or deactivate this function.

Ransomware Protection

There is no doubt that ransomware is one of the most important security threats that we can find on the web. It is a type of malware that aims to encrypt our files and systems and request a financial ransom in return to be able to access them again.

Windows Defender has a feature that helps improve protection against ransomware. However, folder access control is disabled by default. You can activate it if you go to Windows Security, Virus and threat protection and there you enter Ransomware Protection and enable the function.

Protect Windows beyond Microsoft Defender

You should keep in mind that using Microsoft Defender is very important for security, but that in itself does not guarantee being completely protected. It is essential to take certain measures and apply some tips to minimize the risk of suffering some type of attack. Therefore, after having correctly configured the Windows antivirus, we also want to give some more safety tips.

Something essential and that cannot be missing is having Windows correctly updated. This will prevent vulnerabilities that can be exploited by attackers. In fact, many types of viruses and malware generally affect it due to security flaws that are not corrected, so we can reduce the risk a lot.

To update Windows you have to go to Start, enter Settings and access Windows Update. It will automatically show you possible files pending update. It is something that you should do periodically, to always have the latest versions available.

Use only safe apps

Another important issue is to use only programs that are reliable and safe. You should download them from official sites and avoid doing so from third-party pages or through links that may be scams and contain malware that infects your computer. Hackers can sneak apps that appear legitimate but are actually scams.

You should also apply this when installing any add-on. For example extensions for the browser or for any application that you have installed in Windows. Regardless of whether or not you have Microsoft Defender installed, you can make the mistake of installing a fake program and you should avoid that.

Protect your network and other devices

Windows Defender is going to focus on protecting the security of your system. However, you may have problems with the network you connect to or with any other device that you are going to connect to the computer, such as a USB memory. Therefore, it is essential that you maintain security in all cases.

You must protect your wifi network and thus prevent intruders from affecting performance and security. Always use a good key for the wireless network, a good current encryption (avoid the obsolete ones, such as WEP or WPA and use WPA-2 or WPA-3) and also a good password to enter the configuration of the router.

But in addition, the same protection that you use for the computer must be applied to any other device. Protect storage memories, mobile devices, printers… All of this can affect, in one way or another, the security of Windows.

Avoid making mistakes

But if there is something essential to be protected and not have problems, it is to avoid mistakes and maintain the common sense. We can say that most cyber attacks will require the victim to fall into some kind of trap and that affects security. Hackers can launch baits for this purpose and can steal data, passwords or cause malfunctions.

A very common mistake is downloading files that arrive by email without knowing if they are really reliable or not. This is a fairly common entry route for malware. It’s also a mistake to log into unprotected public Wi-Fi networks or trust sites that may be fraud.

In short, as you have seen Windows Defender is a key piece to maintain your security. We have explained how you can configure it correctly to maximize protection. However, you have also been able to see that it is not enough just to have an antivirus and that you will have to avoid certain errors and optimize security.
