Is an antivirus mandatory to protect yourself?

An antivirus is not essential, but it is strongly recommended to have it. For some users who know very well what they are doing, this will not be necessary: ​​by following good practices such as always visiting trusted sites, using complex passwords, or even not downloading software from sources. not having an established reputation, you can avoid many threats, and even never catch a virus on your computer. However, not everyone is aware of these practices and it is even rather the opposite: to protect your loved ones or your family who do not necessarily know how to use a computer at their fingertips, it may be necessary to install an antivirus because they will not necessarily show the same vigilance. And on his smartphone? We cannot say that there are as many risks as with Windows in particular. On the other hand, viruses for Android do exist and even on a very secure iPhone, it is not impossible to be scammed if you are not careful. This is why it is also recommended to protect the device from someone who does not have these good reflexes naturally.

Antivirus: how to choose?

To choose the right antivirus, it is essential to observe a few rules. The most important is to choose software that offers several types of protection. If an antivirus can only protect your computer from known viruses, the protection will be too weak, because it is necessary to also be able to identify malicious software that is not yet known to the databases. How is this possible? For example by monitoring the activity of your computer. If the antivirus detects that software it does not know, or which is known to be suspicious, is modifying files on your computer, it can alert you. It must also be able to protect you against other types of threats such as phishing, which is a technique based solely on fake sites or emails to deceive the vigilance of the user. Finally, it must have tools that allow you to make secure online purchases, for example by preventing hackers from intercepting what you type on your keyboard.

Free or paid antivirus: what are the differences?

There are free and paid antiviruses. Some are even integrated directly into the system of your PC or smartphone. What are the differences compared to paid antivirus? Free antiviruses are effective against the most common types of threats like spyware or viruses. And that’s often the only features it offers, sometimes with a ransomware monitoring tool. Conversely, a paid antivirus, or even better a security suite will offer more complete functionalities, such as more proactive defense shields, an intelligent firewall, tools for protecting banking or commerce sites, an extension or a secure browser to surf safely away from fraudulent sites or hosting malware … Some security suites today * i even offer limited or unlimited access to a VPN.

What are the main advantages of antivirus software?

Antivirus helps protect yourself against malware. It can detect them if it recognizes their signature in its databases which are now often enriched by the cloud for more reactivity. Above all, it can block them, even if they are too recent to be recognized. In this case, it will detect suspicious behavior, or execute the code in an environment isolated from the system to observe its operation. Today, antiviruses also make it possible to protect against ransomware by monitoring the files often targeted by this software such as Documents, Images, etc.

Antivirus also protects you against hacking and data theft, with tools that prevent your keystrokes from being captured or your webcam from being used by unreliable software. It can detect intrusions on your Wi-Fi network and analyze its security level.

Thanks to the intelligent firewall, the antivirus protects you against the exploitation of vulnerabilities that may remain in your system or in your software that is not necessarily updated.

Finally, it detects fraudulent sites or suspicious emails that try to pass themselves off as your bank or an administration in order to extract personal data.

You can also opt for a full suite that goes beyond just malware protection. For example, Avast Ultimate brings together Avast Premium Security Antivirus, Avast SecureLine VPN, AntiTrack Tracking Device Blocker and Cleanup Premium in a single package to optimize your computer’s performance.

What is the concept of antivirus software? To fully understand it, we first need to know what a virus is. On a computer, the principle is almost the same as in real life. Let’s say your PC or Mac is your body. When it is infected with malicious software, or malware, it is as if your health is deteriorating due to an illness. Except that here, it is therefore the machine which becomes unusable.
