The internet is full of malware and viruses. Often, some malicious code still lingers somewhere on your device, even if you have deleted all infected files. As a result, you can never be percent certain that the virus or malware has been completely removed. To protect yourself against these types of threats, you need a proper virus scanner.

Antivirus software scans your files before you open them, so that a virus does not have the opportunity to infect your system. Most advanced virus scanners also detect non-traditional malware. Examples of this type of malware are adware and spyware. The goal of a virus scanner is to protect your device from viruses and other types of malware. All viruses known to your antivirus program are on this blacklist. As soon as the virus scanner encounters something that has been blacklisted, the program will stop the file and try to delete it.

An antivirus program scans your system in various ways:. Many virus scanners work with blacklists. Essentially, a blacklist is, as it were, a sort of database of all viruses known to the virus scanner. During a scan, antivirus programs instantly compare the files on your computer with the definition files that are on its blacklist.

If it finds a match, it means that a virus on the blacklist is in that file on your computer. The virus scanner then goes into action and isolates the dangerous file. This enables virus scanners to identify new or modified forms of malware, even if they are not yet on the blacklist. Furthermore, a virus scanner should be able to detect whether something is wrong when programs behave suspiciously.

Take a file, for example, that tries to penetrate other files to overwrite their internal code. A good antivirus program picks up this unusual behavior and counteracts it. A disadvantage of heuristics is that a prediction can never be percent accurate. This means that, if a virus is not yet on the blacklist, your antivirus program cannot be sure it is a virus. This could lead the virus scanner to draw the wrong conclusion and may identify a safe file as a virus.

Otherwise, you will just get constant notifications and using your device would become a pain. As with many other types of software, there are both free and paid virus scanners.

So yes, you can opt for and download a free antivirus program to protect your computer. But be aware, there is more to it…. Once you download the software, malicious code will enter your computer and can cause you a lot of misery, when all you were trying to do was to protect your device. To avoid this, we recommend that you make sure you are well-informed and, for example, check reliable reviews before you download such antivirus programs.

Other than the fact that some free antivirus programs contain malware, there is another reason to be wary of free virus scanners. Many free antivirus programs are not nearly as good as paid versions. You will need to, for example, check for yourself that your system is always up to date, and you are less well protected in general.

Fortunately, there are a few very good free antivirus programs out there. In this article we will discuss one that you can use safely. A lot of people think that these are two sides of the same coin, but that is not entirely true.

They perform slightly different tasks. Therefore, it is wise to not only install a virus scanner, but also ensure you have a good firewall. The difference between an antivirus program and a firewall lies in when a malware threat is detected and how it is neutralized. Antivirus programs scan the files on your computer for malware, whereas firewalls protect you from malware, cybercriminals , and other malicious things on the internet before they reach your computer.

Only files and information considered safe can pass through the wall. An antivirus scanner, on the other hand, scans all files already on your computer and eliminates them, even if they have not yet been activated. Many virus scanners do have their own built-in firewall. This means that you install both at once. Getting new software is always difficult, especially when you need to pay for it. How do you know if you are making the right choice? Can you be sure that this virus scanner is better for you than that one?

Here are some things you might want to keep in mind when considering which program is the best antivirus software for you. The most important characteristic of a good antivirus program is, of course, that it does its job properly. Does the program identify the majority of viruses? Can it disarm malware before it affects your computer? You just want to know. Fortunately, there are many online reviews from people who have already done the work for you.

The antivirus software is carefully tested so that you know what to expect. When purchasing software, it is important to check that the program works on your device.

Therefore, you should check whether the antivirus program is compatible with your operating system. A software program that is easy to use and easy to navigate makes a difference. A user-friendly interface is a must if you want to easily find your way around the program and uncover the various features. Maybe you want to regularly view a list of all the actions performed by your virus scanner.

Maybe you prefer to decide for yourself whether a file is dangerous or not before your virus scanner intervenes.

Or, on the contrary, maybe you do not want to notice at all that your virus scanner is running in the background while you are using your device. This has all to do with the user-friendliness of the program and the options available with virus scanner.

Have you run into a problem? Is your antivirus software not responding as it should? If that is the case, it can be very helpful to have a support team available that can quickly and efficiently answer your questions and help solve any issues. Some antivirus software developers offer support, others do not. Of those that offer support, some offer a live chat, while others only offer email support.

The latter can increase the waiting period. Be mindful of what you prefer and take this into consideration. Every virus scanner tries to differentiate itself from its competitors. They do this, among other things, by offering extra options. In addition to a virus scanner, they also offer a password manager , for example, or protection against phishing scams.

Others offer you cloud backup space when you purchase a subscription, or give you a discount on a VPN service. In addition to these extra options, the ability to precisely adjust the settings can also make a difference. A novice user probably wants to get started as soon as possible.

An advanced and more technical user, on the other hand, will like the benefits manual configuration has to offer. Of course, the price of your antivirus software is also an important factor. Ideally, you want to protect your devices as optimally as possible without having to pay too much for what you need. You could consider freeware or opt for more security with a paid virus scanner. As we discussed earlier, some free virus scanners work quite well, but they do come with some risks you need to be aware of.

While you are probably not able to or capable of testing different virus scanners, others are. You can find numerous reviews online. On Google Play, for example, people often rate the apps they download. Sometimes they include comments, which can be a very useful source of more details. On forums such as Tweakers, technical users discuss the effectiveness of specific virus scanners.

This can also be a good resource if you speak some of the lingo. And on official websites like ours you will find well thought-out and complete reviews of the best and most well-known virus scanners. Make smart use of these resources before making your choice. In this way, you will find the best antivirus program for you. If you are not sure which virus scanner is the best one for you to purchase, we are happy to be of help. Here are two reliable virus scanners that we confidently recommend.
