ESET Online Scanner is an online malware removal tool, service for a one-time online scanning of a computer for viruses, trojans. It identifies spyware and eliminates security threats. Considered to be an alternative version of ESET Internet Security (or Nod32) desktop app.

Despite the word “online” a special Windows app is required for its work. Without downloading the app it's impossible to use the service.

Plus, all Nod32 antivirus databases are available online and you need a stable Internet connection for scanning.

You can enable potentially undesirable apps detection in the settings. It isn't required and, as a rule, its activation can trigger a false alarm. However, it won't cause any damage and actually will just make you double-check those apps: what if suddenly it's really a virus.

All the other scanner settings we advise to leave untouched, and then click on "Scan" button.

Scanning, viewing the results and deleting viruses

All actions are displayed in real time in ESET Online Scanner window. The exact time of scanning isn't displayed immediately and is changed over time. Judging by our experience, online scanning takes from 30 minutes to an hour. You can stop the process at any time by pressing a button of the same name.

If viruses are detected, ESET suggests deleting them. To do this you have to tag the files with a check box and agree on deletion.

Please note that infected files aren't quarantined but permanently deleted, so in case of error you won't be able to retrieve them.
