vírusellenrzése

Vírusellenrzése is a Hungarian term that translates to "virus scanning" or "virus checking" in English. It refers to the process of examining files, programs, and data on a computer or network for the presence of malicious software, commonly known as computer viruses. This scanning is typically performed by antivirus software, which uses various methods to detect threats.

Antivirus programs employ several techniques to identify viruses. Signature-based detection involves comparing the code of scanned files against a database of known virus signatures. If a match is found, the file is flagged as infected. Another method is heuristic analysis, which looks for suspicious patterns or behaviors in files that are characteristic of viruses, even if the specific virus is not yet in the signature database. Real-time scanning continuously monitors system activity, checking files as they are accessed, downloaded, or executed. On-demand scanning allows users to initiate a scan of specific files, folders, or the entire system at their convenience.

The primary goal of vírusellenrzése is to prevent infections, detect existing malware, and remove or quarantine infected files to protect the integrity and security of digital systems and data. Regular and up-to-date virus scanning is a fundamental practice for cybersecurity.
