What actually is an antivirus?
An antivirus program or antivirus software is a tool, with which you can protect your computer or your network from viruses.

Infected files are then quarantined or isolated and cleaned or completely deleted as required.

We'll explain how you do it here .
Why do I need virus protection?
As already mentioned, any computer, smartphone or tablet can now be infected with a virus. It's usually easier than you think. You click on a link that leads to a dubious page or you open attachments that are already infected. There are many ways in which you can get a virus. As technology continues to evolve, there are more and more cyber criminals who develop viruses to spy on data or damage devices.
Especially if you have a Windows computer, you shouldn't worry too much Windows Defender leave. It does its job, but it's nowhere near as good as an antivirus program.
What if a virus infects a computer?
If a virus infects a computer without an antivirus program, it can have a significant impact. Depending on the type of virus, it can delete files, block your access to files, send spam, spy on you, or perform other harmful actions. In some situations it also happens that a computer is only used to infect other systems. As a rule, you do not notice whether you are infected or not. The point of a virus is usually that it goes undetected and infects as many other devices as possible. However, there are also types of viruses that can paralyze or lock your computer.
Types of viruses
Computer viruses are constantly evolving. Because of this, it turns out to be relatively difficult to categorize a computer virus. Usually all types of viruses are considered to be speaking Malware (Malicious Software). As the name suggests, this is malware that can cause significant damage to you and your device. However, over the years viruses have been found in the following Categories divided:
Trojans are found on pretty much all end devices and operating systems. It is a very harmful virus that is mainly used to spy on the user. Trojans are often sent in attachments and usually go unnoticed by the user. However, this virus also likes to hide in a program or app. It is usually quite difficult to remove a Trojan, especially if you don't have an antivirus program.
This type of virus is a script that is built into websites. These viruses are written in the most common programming languages. The browser therefore does not regard this as a virus. These viruses are also not clearly recognizable for the end user. Often these viruses then spread on the computer to send spam e-mails or to delete files.
These viruses infect computers through programs or files in which they are manifested. As soon as you open the program or the file, the virus is activated. This type of virus is mainly caught when downloading certain programs or files from dubious websites. Ultimately, this virus can also cause considerable damage to the end device.
A macro virus behaves like a Trojan horse or a program virus. The only difference is that this virus is found in Word or Excel files as a macro. This type of virus spreads over the Internet through email or file downloads.
This particular type of computer virus infests itself on a computer and spreads on its own. This virus usually spreads very quickly and is not activated by the user. Computer worms are often present in e-mails (e.g. chain e-mails) and thus not only infect your own device, but many others.
What does an antivirus do?
As mentioned earlier, an antivirus is software that protects your computer from viruses. The program already prevents a virus from being downloaded, detects viruses in the files and even removes all malware - i.e. harmful software. Originally, antivirus programs were only intended to remove viruses from computers. Nowadays, however, an antivirus program protects almost every operating system from keyloggers, browser hijackers, Trojans, worms, rootkits, spyware, adware, botnets and adware.
How does an antivirus work?
An antivirus is usually running in the background as a process. He checks all files, servers or mobile devices. Thus, an antivirus can detect malicious programs or files. Many antivirus programs also include real-time protection. This means that your device is protected XNUMX/XNUMX and protects you from all the dangers of the internet. So as soon as you are connected to the internet, your antivirus program protects you from clicking on fake websites or downloading dubious content. This usually happens in the form of a warning or an immediate quarantine if the file or program is particularly dangerous.
This Features runs an antivirus program:
- Virus Scanner
The virus scanner is the most important part of any anti-virus protection. Files, folders and entire systems are scanned and checked for malware. The consumer can also decide for himself when a scan is carried out. It should also be possible to set when the scans should be carried out automatically. So you always stay protected.
- Remove malware
As soon as malware is found on the end device, a virus scanner should be able to remove it. The consumer is often given the choice: either quarantine the infected file, clean it or delete it.
- Real-time protection
In times when there are a lot of fake websites, a virus program should have real-time protection. This prevents the user from clicking on dubious websites from the outset (e.g. those containing viruses or unwittingly downloading files). A virus scanner should also scan attachments from e-mails and messages.
- Regular updates
This point should actually be taken for granted. An antivirus program should update itself regularly to get the latest virus signatures. If you don't keep your antivirus up-to-date, it will be out of date and you will not be protected from new viruses.
Antivirus: Free or Paid?
There are enough antivirus programs. This naturally raises the question of which anti-virus 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.
Free Antivirus: Are They Good?
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 annoy you with advertisements. This is how most free antivirus programs finance themselves. And that's a big disadvantage. Antivirus protection should protect you from adware and not bombard you with it.
Another disadvantage of a free antivirus is functionality. Most of the time these are very stripped down. Often you cannot perform automatic scans and always have to do this manually. In addition, updates are often not automatic. This means that the virus database is then out of date and protection is hardly guaranteed.
Advantages of free virus scanners
The biggest advantage of free antivirus software is - as the name suggests - the price. Because it's free. Free virus programs usually offer basic protection for your computer or network.
Free antivirus programs are mostly part of one free trial period for paid programs. In this case, you often get the 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 you can then decide whether this program is right for you.
Disadvantages of free virus scanners
As already mentioned, a free virus scanner often only offers that minimal of security. Additionally, most free programs contain pop-ups and other forms of Advertisingthat can be quite annoying in the long run. With completely free antivirus scanners you also have to forego additional functions. A good example of this is Windows Defender for Windows users. It offers basic protection for every Windows PC, but you have almost no additional functions.
