What is the ESET Online Scanner and how does it work?

The ESET Online Scanner is a free, web-based tool designed to scan and remove malware from computers. Users can run it directly from their web browsers without the need for installing comprehensive antivirus software, making it a convenient option for one-time scans or a second opinion on a system's health. Upon activation, it downloads a temporary set of components necessary for the scanning process. It then uses ESET's signature database to detect viruses, worms, trojans, spyware, and other malicious threats. The scan can be customized to target specific files or directories, and there are options for varying levels of thoroughness. Once the scan is complete, the tool provides a report detailing any detected threats and offers options to clean or quarantine the infected files, thus enhancing the user's system security.
