Antivirussystemen

Antivirussystemen, often referred to as antivirus software, are computer programs designed to detect, prevent, and remove malicious software. This malicious software, commonly known as viruses, can include a wide range of threats such as malware, spyware, ransomware, and worms. These programs work by scanning files, programs, and system memory for known patterns of malicious code, often referred to as signatures. When a suspicious file or program is detected, the antivirus software can quarantine it, delete it, or attempt to clean it.

Modern antivirussystemen employ several methods to protect systems. Signature-based detection is the traditional approach, relying on a database of known virus signatures. However, as new threats emerge constantly, heuristic analysis is also used. This method looks for suspicious behaviors or characteristics of unknown files that might indicate malicious intent, rather than relying solely on pre-existing signatures. Real-time protection continuously monitors system activity and scans files as they are accessed or downloaded. Regular updates to the virus definition database are crucial for antivirussystemen to remain effective against the latest threats. Many antivirus solutions also offer additional features like firewalls, anti-phishing tools, and identity theft protection.
