F-Secure Online Scanner review
A focused free scanner for Windows cleanup, not ongoing protection or web scanning.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
F-Secure Online Scanner is a free Windows utility for detecting and removing viruses, malware, and spyware in a one-time scan. It suits Windows users who want to check a PC and remove threats without choosing a paid plan. The vendor describes it as a standalone cleanup tool rather than ongoing protection, so it is not a replacement for software intended to monitor a system continuously.
The scanner runs from a downloaded .exe file, rather than through a browser. F-Secure states support for Windows 10 version 22H2 or newer on x64 systems and Windows 11 version 24H2 or newer on ARM64 systems. The vendor also advises uninstalling other antivirus programs before running it, a consideration for users who already have security software installed. Its scope is computer scanning and cleanup; it is not described as a service for submitting individual files or URLs for online analysis.
There is no paid tier to compare: the product is free and built around a one-time scan and threat removal. That narrow scope makes it a fit for solo users or small organizations seeking a straightforward cleanup utility on supported Windows systems. Choose a different product if you need persistent protection, browser-based file or URL scanning, or broader online analysis. For a one-off check and removal task, F-Secure Online Scanner keeps the offer focused on those needs.
