What Security Threats Can Antivirus Protect Against?
The best antivirus software provides comprehensive protection against various digital threats, including:
Viruses – Malicious programs that replicate and can damage your computer, steal personal information, or destroy data.
Worms – Self-propagating malware that spreads without user interaction, often creating botnets (networks of infected computers) to launch attacks or send spam.
Trojans – Disguise themselves as legitimate programs to deceive users. Once installed, they allow attackers to take control of your computer and steal information.
Ransomware – Encrypts your files and demands payment for recovery, with no guarantee that files will be restored even after payment.
Spyware – Collects your personal information such as passwords, credit card numbers, and browsing history, while tracking your activities.
Adware – Displays unwanted advertisements on your computer, generating revenue for creators while potentially collecting personal information.
Rootkits – Designed to hide from detection, they can compromise your system to steal data or attack other computers.
Keyloggers – Record everything you type, including sensitive information like passwords and credit card numbers.

How Does Antivirus Software Work?
Antivirus software protects your computer by scanning for viruses and removing them. Premium solutions can prevent infections and neutralize attacks in real-time. The most effective antivirus programs employ a multi-layered approach to security:
Artificial Intelligence – Advanced antivirus solutions leverage AI to identify emerging threats and adapt to new attack patterns.
Signature-Based Detection – This fundamental method compares files on your device against a database of known virus signatures to identify established malware.
Heuristic-Based Detection – Rather than looking for specific viruses, this approach identifies suspicious behaviors and code patterns that resemble malware, catching previously unknown threats.
Behavior Monitoring – Continuously tracks your system’s operations, detecting unusual changes or activities that might indicate an infection.
Sandboxing – Runs suspicious programs in an isolated virtual environment where they can be safely analyzed without risking damage to your actual system.
