Finding the right anti-virus software

Translation: machine translated

Everyone needs it and almost everyone has it - an anti-virus programme. Questions often arise such as: Which is the right and best product for me? What should I look out for when buying? What does an anti-virus programme actually do? What is the difference between a computer virus, a worm and a Trojan?

I would like to explain these questions to you as briefly as possible and in a way that even the average consumer can understand. The experts among you are welcome to add articles in the comments.

What does an anti-virus programme do anyway?

In simple terms, the anti-virus programme guards access to the computer. The data allowed through by the firewall is checked by the anti-virus programme for viruses, worms and Trojans.

What is the difference between a computer virus, a worm and a Trojan horse?

Computer virus

A computer virus cannot spread by itself, but is triggered by the user without their knowledge. Once this has happened, the virus nests itself in documents and programmes. Just like a parasite that clings to its host. The goal is pure destruction.

Trojans

They usually hide in useful, everyday programmes and target private data. Bank details or credit card numbers are very attractive. The Trojan collects these and sends them to the creator. A Trojan can also be used to access the computer directly.

Worm

In contrast to conventional viruses, worms spread automatically by copying themselves. For example, they send themselves by email. They also focus on destruction.

What should I look out for when buying

Most antivirus programs are available with a different number of licences, i.e. how many devices you can install them on. The validity period of the licences can also vary. It is best to refer to our information in the specifications. You will find the required information under Duration and Number of licences.

Which is the right and best product for me?

AV-Test, also known as "The Independent IT-Security Institute", carries out anti-virus tests at regular intervals. The following link will take you to the test results: https://www.av-test.org/de/antivirus/privat-windows/. My three favourites achieved excellent results. Bitdefender should be proud, as they achieved the highest possible score. The only drawback: Bitdefender is now only available as an ESD version. Kaspersky and Norton are hot on Bitdefender's heels - but both were criticised for small losses in speed. However, it is highly questionable whether these are really noticeable in everyday use.
