How are virus protection programs programmed

Additional antivirus programs: do you need it?

Last updated on December 6, 2018 by Jürgen Voskuhl

I am often confronted with additional antivirus programs with numerous customers as well as in the private sphere. But what are computer viruses actually? And do you really need additional software?

Everyone has probably heard of computer viruses. These are programs that change the way a computer works and spread from computer to computer. The changes a computer virus makes are mostly malicious in nature. For example, data is changed or deleted.

An antivirus program (also known as AV software, virus scanner or virus protection program) is software that is designed to detect, block and, if necessary, eliminate computer viruses. A double-digit number of such products is common on the market. An anti-virus program is also integrated in the Windows operating system Defender is called.

The Defender used to be in the lower ranks in comparative tests. That changed at the end of 2016: since then, the detection rates have increased significantly and are on par with commercial competing products. With the Windows Creators Update in April 2017, Microsoft has the Defender also missed a new user interface.

The idea that the manufacturer of an operating system can best protect it is somehow obvious, doesn't it?

In all of the current test reports that I read, the Windows on-board tool comes up Defender gone quite well. This is also the case in current tests by AV-Test. The AV-TEST Institute regularly makes the latest tests and current research results available to the public on its website.

I think you don't need additional anti-virus software anymore!

So when you buy a new Windows PC or a new notebook, it is best to throw away the additional anti-virus software that comes with the machine!
By the way, you don't have to do anything else: The Windows on-board tool Microsoft Defender activates itself.

Your own behavior is crucial

Of course, it is best if an antivirus program does not work at all. As a computer user, you can make a significant contribution to this:

  • Make sure that your operating system and all of your programs receive the latest updates on a regular basis.
  • Avoid doing anything that could put your computers at risk.
    This includes opening unknown email attachments, visiting unknown websites and downloading software from untrustworthy websites or from P2P file-sharing networks.
  • Never open file attachments that have not been checked.
    Even if the files are apparently harmless such as pictures, documents or other files: If you are not sure, ask the sender.
  • Restrict your rights on the computer.
    Even if you are an experienced IT professional: You do not need to have administrative rights for daily use and normal use.
