What is an antivirus?

Why do I need virus protection?
As already mentioned, every computer, every smartphone or tablet can now be infected with a virus.This is usually easier than you think.You click on a link that leads to a dubious side or you open attachments that are already infected.There are many ways to catch a virus.With the constantly developing technology, there are also more and more cybercriminals that develop viruses to spy on data or to cause damage to devices.
Especially if you have a Windows computer, you shouldn't rely too much on Windows Defender.He does his job, but is by no means as good as an antivirus program.
What happens if a virus infected a computer?
If a virus infected a computer without an antivirus program, this can have a significant effect.Depending on the type of virus, deleting this files, blocking access to files, sending spam, spying on, or carrying out other harmful actions.In some situations it also happens that a computer is only used to infect other systems.As a rule, you don't notice whether you are infected or not.The meaning of a virus is usually that it is not discovered and can infect as many other devices as possible.However, there are also types of viruses that paralyze or lock your computer equally.
Types of viruses
Computer viruses constantly develop.Therefore, it turns out to be relatively difficult to categorize a computer virus. In der Regel spricht werden alle Types of viruses als Malware (Malicious Software) bezeichnet.As the name suggests, this is malware that can harm you and your device considerable damage.Over the years, however, viruses have been divided into the following categories:
Trojanerscript virus program virus -computer computer worms
Trojans are available on almost all end devices and operating systems.This is a very harmful virus that is mainly used to spy on the user.Trojans are often sent to attachments and usually remain unnoticed for the user.This virus also likes to hide in a program or app.As a rule, it is quite difficult to remove a Trojan, especially if you don't have an antivirus program.
This type of virus is a script that is integrated on websites.These viruses are written in the most common programming languages.So the browser does not see them as a virus.These viruses are also not clearly recognizable for the end consumer.Often these viruses then spread on the computer to send spam emails or delete files.
These viruses infect computers via programs or files in which they are manifested.As soon as you the program or.The file opens, the virus is activated.This type of virus is particularly captivated when you download certain programs or files from dubious websites.In the end, this virus can also cause considerable damage to the end device.
A macrovirus behaves like a Trojan or a program virus.The only difference is that this virus is Word or Excel files as a macro.This type of virus spreads via the Internet via emails or the download of files.
This special type of computer virus nests and spreads and independently.Usually this virus spreads very quickly and is not activated by the user.Computer worms are often in emails (z.B.Chain emails) and therefore not only infect your own device, but many others.
What does an antivirus do?
As already mentioned, an antivirus is software that protects your computer from viruses.The program already prevents downloading a virus, tracks down viruses in the files and even removes all malware - i.e. harmful software.Originally, antivirus programs were only intended to delete viruses from computer.Nowadays, however, an antivirus program protects almost every operating system from keyloggers, browser hijackers, trojans, worms, rootkits, spyware, adware, botets and adware.
How does an antivirus work?
An antivirus usually runs in the background as a process.He checks all files, servers or mobile devices.An antivirus can thus track down harmful programs or files.Many antivirus programs also contain real -time protection.This means that your device is protected and protected from all the dangers from the Internet. Sobald du also mit dem Internet verbunden bist, schützt dein Antivirenprogramm dich davor, auf gefälschte Webseiten zu klicken oder dubiose contentse herunterzuladen.Usually this happens in the form of a warning or an immediate quarantine, the file or.the program be particularly dangerous.
An antivirus program carries out these functions:
Virus scanner virus scanner is the most important of every antivirus protection.Files, folders and entire systems are scanned and checked for malware.The consumer can also decide for themselves when a scan is carried out.You should also be able to set when scans will be done automatically.So you always stay protected.
Removing Malware Obald malware on the end device is found, a virus scanner should be able to remove them.The consumer is often given the choice: either the infected file is placed under quarantine, clean them or delete them.
Reality protection Especially in times when there are many fake websites, a virus program should have real -time protection.This prevents the user from clicking on dubious websites from the outset (the Z.B.Contain viruses or download files).A virus scanner should also scan attachments from emails and messages.
Regular updates This point should actually be a matter of course.An antivirus program should update yourself regularly to get the signatures of the latest viruses.If you don't constantly update your antivirus program, it is outdated and you are not protected from new viruses.

Antivirus: free or chargeable?
There are enough antivirus programs.Of course you ask yourself the question of which antivirus protection you need for your device.You have to know which additional functions you would like to have and, above all, how safe antivirus programs are.That is why a distinction is made between free and paid antivirus programs.
Antivirus for free: they are good for what?
Most free antivirus programs have a virus scanner, but are usually not sufficient for all -round protection for your device.Furthermore, many free virus scanners have the disadvantage that they are bothering you with advertising.This is how most free antivirus programs finance.And that's a big disadvantage.Antivirus protection should protect you from adware and not bomb it with it.
Another disadvantage of a free antivirus is the functionality.Most of the time they are very slimmed down.You can often not carry out automatic scans and always have to do this manually.In addition, updates are often not automatic.This means that the virus database is then outdated and hardly any protection is guaranteed.
In short: there is no really good free antivirus protection.
Advantages of free virus scanners
The biggest advantage of free antivirus software - as the name suggests - is the price.That is for free.As a rule, free virus programs offer a basis for protection for your computer or your network.
Free antivirus programs are usually part of a free test period for paid programs.In this case, you often get full range of functions for a certain period of time to test a paid antivirus.Of course, this has a big advantage: you get all the functions for free and can then decide whether this program is the right one for you.
Disadvantages of free virus scanners
As already mentioned, a free virus scanner often only offers minimal security.Furthermore, most free programs contain pop-ups and other forms of advertising that can be quite annoying in the long run.With completely free antivirus scanners, you also have to do without additional functions.A good example of this is for Windows users of Windows Defender.It offers basic protection for every Windows PC, but you have almost no additional functions.
