What is a Virus Scanner?
A virus scanner is security software that detects, quarantines, and removes malicious software such as viruses, trojans, worms, and other malware from servers and websites.
How Does Virus Scanner Work?
In a web hosting context, virus scanners continuously monitor files uploaded to the server, email attachments, and website content for known malware signatures and suspicious behavior patterns. When a threat is detected, the scanner can automatically quarantine the infected file, notify the server administrator, or remove the malicious code entirely. Modern scanners use both signature-based detection and heuristic analysis to catch new and evolving threats.
Running a virus scanner on your hosting server is essential for protecting both your website and its visitors. Compromised websites can unknowingly distribute malware to visitors, leading to blacklisting by search engines and browsers. Many hosting providers include server-level scanning tools like ClamAV or Imunify360 as part of their security suite to provide an additional layer of defense.
