VirusScan is a term that broadly refers to the process of detecting and identifying malicious software, commonly known as viruses, within a computer system or network. This process is typically carried out by antivirus software, which scans files, programs, and other data for known patterns or signatures of malware. When a suspicious file is detected, the antivirus software can take various actions, such as quarantining the file, deleting it, or attempting to repair the infected code.

The effectiveness of VirusScan relies on regular updates to the antivirus software's database of malware signatures. These updates are crucial because new viruses and other forms of malware are constantly being developed. Without updated signatures, the antivirus software may not be able to recognize or protect against the latest threats. Beyond signature-based detection, many modern antivirus programs also employ heuristic analysis, which examines the behavior of programs to identify potentially malicious activities even if a specific signature is not yet known.

The importance of VirusScan extends to personal computers, mobile devices, and enterprise networks. Regular scanning helps prevent data loss, system corruption, and unauthorized access to sensitive information. In a business context, a robust VirusScan strategy is a fundamental component of cybersecurity, protecting against financial losses and reputational damage that can result from malware infections. Users are generally advised to run VirusScan scans periodically and to ensure their antivirus software is always up-to-date.
