2 – Mon­i­toring with antivirus soft­ware and firewall

What kinds of “access doors” are open on your device, and which kind of viruses can pass through? Prac­ti­cally none, as long as you have acti­vated a fire­wall and installed antivirus software.

The most impor­tant points to remember:

  • Use antivirus soft­ware and acti­vate its auto­matic update function.
  • You should peri­od­i­cally check your device for virus infec­tions by run­ning a com­plete system check.
  • Acti­vate the fire­wall that comes with your Win­dows or macOS before you con­nect your device to the Internet or another network.

How to proceed

Use antivirus soft­ware and a fire­wall, which is con­tin­u­ously kept updated with auto­mated updates so that you are always pro­tected against the latest risks.

Win­dows 10 and Win­dows 11 are sup­plied with a fire­wall, and their “Win­dows Defender” antivirus soft­ware is acti­vated by default. This ensures you are per­fectly protected.

To use addi­tional pro­tec­tive func­tions, such as a parental con­trol con­tent filter, you can also use any of the fol­lowing list of prod­ucts (which is not com­pre­hen­sive), some­times even free of charge:

Mal­ware infec­tion - what now?

Should you sus­pect your device is infected with mal­ware or if your antivirus soft­ware noti­fies you of such an infec­tion, you can find addi­tional infor­ma­tion on what you can do here.


When users are surfing the Internet on their com­puter, tablet or smart­phone, invis­ible “access doors” (ports) are opened on their devices to com­mu­ni­cate. These offer a target for attackers from the Internet. A fire­wall installed will close these doors as much as pos­sible and will mon­itor all data traffic between your devices and the Internet. Your fire­wall will alert you if it dis­covers any “sus­pi­cious” net­work traffic.
