How Antivirus Software Prevents Cyber Threats

Now that we have a quick understanding of everything we worry about when cyber threats are involved, we'll show you exactly how antivirus software can prevent them from happening in the first place.

• Reactive File Scan: Antivirus software scans a database of known malware before opening a new file.
• Full system scan: Also, the software scans the entire device to detect data leaks, but this process takes much longer than scanning individual files.
• Web browsing protection: Files are not the only ones that contain viruses. Even the simplest antivirus software scans URLs and sites for potential risks.
• Real-time prevention: Antivirus software not only scans for threats on-demand but also automatically and continuously to prevent malware outbreaks.
• Rapid infection and threat removal: When antivirus software detects a malware, it quarantines the malicious files in a secure folder so that users can see them manually.
• Threat detection rate: If antivirus software is involved, the possibility of detecting threats is fully built into the database. Each company maintains its own malware database, which is called the known threat database and is constantly updated. Detection rate is how accurately the software labels clean files and potential threats, taking into account false positives and false positives. Companies such as AV-TEST, NSS Labs, and A.V Comparisons are independent, validated laboratories that guarantee these rates for testing antivirus software on multiple devices and operating systems.

How antivirus software detects cyber threats

We know that antivirus software uses a database of malware to display on your device, but how do you detect threats?

• Behavior-based detection: Most antivirus software these days uses behaviour-based detection in addition to signature analysis. This is explained in detail below. Behaviour-based detection looks for code that makes changes to the device without permission, or anything that seems suspicious. Unlike signature analysis, behaviour-based detection does not rely solely on a database of known malware, it can also detect new malware.
• Signature analysis: Signature analysis compares threat signatures or “fingerprints” to malware databases when compared. However, if the threat is not yet in the database, the signature analysis will not be able to detect the threat on its own. As a result, much such software has been switched to behaviour-based methods.
• Heuristic-based scans: This type of scan detects what is called a "polymorphic virus." This is a mandatory malware whose code has been modified to evade detection.
• Machine learning: To identify threats, machine-learning processes data in files and uses computational power to detect patterns.
• In-memory scan: An in-memory scan means that a potential threat is investigated after it is already on your computer or device.
• Sandboxing: Finally, sandboxing, also known as quarantine, means isolating suspicious files in a secure part of the operating system so that the rest of the device cannot be attacked.

Antivirus software extra

In addition to most of the features of antivirus software, many companies bundle this software with other services such as VPN, fraud prevention, and parental controls. However, if your antivirus software exists alone, you will have to pay more.

• Parental controls: Parental controls usually allow parents to control what their child is looking at online, what they are searching for, and how they use a particular device.
• Firewall or network protection: Firewalls scan your entire network, not just device threats. These are usually bundled with antivirus software for free, but may only be included in additional advanced packages. In essence, network protection scans your network for devices and alerts you to potential intrusions. 3
• Secure browsers: Secure browsers vary from software to software, but at the very least, make sure you are not visiting malicious websites or clicking on malicious attachments.
• Password Manager: Password manager stores all usernames and passwords in an encrypted vault. It also performs password audits and generates new passwords for old, weak, or recurring passwords.
• Encrypted cloud storage: Some packages include a finite amount of encrypted cloud storage for all kinds of files, including sensitive information.
• System performance optimization: Some software provides optimization tools to improve browsing speed and maintain all previous programs, but generally, these do not require additional fees. I don't think so. Instead, set the software to update automatically and manually clean up the files to free up space.
• Personal information theft protection: Some software also provides fraud protection. This is software that scans credentials in the major criminal and financial fields. This program may also include fraud insurance.
• VPN: Last but not least, a VPN is a virtual private network that hides the device's private IP address and encrypts web activity to mitigate the hacking vulnerability. For more information, see VPN's largest review.
