To protect your Windows computer from viruses and other malware, you should consider the following.

Security updates[Bearbeiten | Quelltext bearbeiten]

Microsoft releases security updates for Windows once a month. With it known security gaps are closed. These should be installed absolutely.

Press the "Windows Key" and open the settings via the "Gear Wheel"
Click on "Update and Security"
This is what it should look like - Windows is up to date

Start menu

  • Press the "Windows Key"'
  • Open the settings via the "Gear Wheel"'.

Windows Update

  • Click on "Windows Update" in the lower left margin.
  • This is how it should look - Windows is up to date.

Functionality updates are to be distinguished from this. These are optional and not security relevant. Therefore, they do not need to be installed immediately. Waiting half a year is not a problem.

Example of an optional functionality update.

Virus protection[Bearbeiten | Quelltext bearbeiten]

Windows 10 has a built-in virus protection with Microsoft Defender by default. The level of protection provided by Windows Defender is considered to be sufficient. No additional virus protection needs to be installed.

More info[Bearbeiten | Quelltext bearbeiten]

Only one antivirus program should be installed on the device at a time. If you install an additional antivirus program, Microsoft Defender will be automatically disabled. However, if you want to use Microsoft Defender, be sure to uninstall all other antivirus programs. Do not install more than one additional antivirus program under any circumstances!

Antivirus programs also need regular updates. If you have installed a fee-based antivirus software and your subscription has expired: uninstall the program. Antivirus programs without updates are a security risk.

In addition to fee-based antivirus programs, there are also many free alternatives. These free alternatives may rely on advertising or collect user data. In any case, rely on a reputable virus protection. There have been instances of malware masquerading as antivirus programs. If in doubt, ask the ZIM.

Antivirus programs are important for safe travel on the Internet. Many antivirus programs come with packages in the form of other programs that you may not need. Email scanners, VPN clients, password managers and PC cleaners should therefore be uninstalled unless absolutely necessary.
