We all know that the Designed to keep your device protectedBut have you ever wondered how exactly this is done? In this article, we’ll take a look at how antivirus software actually works.
Real time alarm:
When it comes to defending your computer and monitoring the files on your system, antivirus software has a few different ways to do this.
The first is the manual scanning of all files on your system, looking for anything suspicious. As these scans can be very long to begin with, and although using smart procedures over time to skip any files that have not changed since the last scan greatly reduces the initial long wait times, most applications also offer some kind of (scan) mode. Rapid), which as the name suggests is just a quick manual scan.
The second pillar of antivirus defenses is the real-time component, which examines the files being introduced to your system, and the processes that are running, in other words if the program detects something bad in your system, it will intervene.
Using both methods, antivirus software relies on what is known as (definitions) – a library of existing malware signatures – where these definitions are updated as closely as possible through updates to the antivirus program, usually on a daily basis (or even hourly). ).
And no matter how fast definition updates are delivered, there are always newly introduced bits of malware that haven’t been seen before, which is why any good antivirus program will use heuristic technology, and that means monitoring suspicious or similar behavior to malware. In processes or files on the host computer, in order to discover something new that was not yet present in the program definitions.
Real-time protection is really the key to defending your computer, with the goal of ensuring that malware doesn’t access it while you use your daily computing.
It can be helpful to manually scan the system with your antivirus program every now and then (or schedule this to happen), because there’s a chance it might pick up something that wasn’t there previously due to updated definitions later.
In fact, this may not be a scenario, and strictly speaking, you may never want to run manual scans but sometimes it doesn’t hurt for safety.
When a piece of malware is found on your device, the antivirus app will take immediate action, and hopefully, it will stop any malicious processes in its tracks there so as not to harm your system.
When it comes to particularly dangerous malware, for example, ransomware, sometimes the process doesn’t stop completely, which could mean that ransomware is able to encrypt (we only hope) a small number of files.
The point here is that in some rare cases, the damage is not stopped immediately, but the antivirus must intervene very quickly and the losses should be minimal.
As part of caring for your system, good antivirus software will provide additional layers of defense – like the ransomware shield to defend against that particularly bad strain of malware.
In general, the antivirus application will also protect your browsing with specific actions, by popping up warnings and preventing you from visiting any webpages that may carry malware or phishing vehicles, to name a few.
