Overview

Antivirus software is a type of software that can detect , remove , and prevent viruses and other malicious programs. It can be installed on our devices and regularly scans our files and programs to detect and eliminate any suspicious or dangerous content. It also provides real-time protection while we access the internet, intercepting and blocking any websites or downloads that may contain viruses or malicious code. By using antivirus software, we can effectively enhance the security and stability of our devices and protect our personal information from cyber attacks.

What are the functions of antivirus software?

① Prevent virus infections

Antivirus software can scan and intercept potentially virus-infected content when you open suspicious files or links, thereby preventing your device from being infected.

② Remove viruses

If your device has already been infected with a virus, antivirus software can help identify and remove the virus, restoring normal operation to your device.

③ Guard against other threats

In addition to computer viruses, there are other types of malware such as spyware, ransomware, and Trojans that can pose risks to your device and personal information. Antivirus software can identify and block these threats, protecting your privacy and data security.

How does antivirus software protect your device?

There are generally two main approaches to how antivirus software works: signature-based and behavior-based. Signature-based antivirus software identifies malicious software by comparing it to known virus signatures or fingerprints. This method requires the antivirus software to constantly update its signature database to match a wider range of virus types. Behavior-based antivirus software, on the other hand, analyzes the behavior and activities of programs to determine if they exhibit malicious intent. This method does not rely on known virus signatures but instead focuses on whether a program attempts to modify system files, access sensitive data, or connect to remote servers, among other indicators, to decide whether to intercept or issue a warning.

Why do we need antivirus software?

① Infections

Your device may get infected with malware, leading to system crashes, data loss, decreased performance, battery drainage, or even remote control by attackers.

② Personal information theft

Your personal information, including banking details, credit cards, passwords, contacts, photos, social media accounts, etc., may get stolen. This information can be used for scams, extortion, identity theft, or sold to third parties.
