What it does
F-Secure Online Scanner is a free downloadable Windows tool that finds and removes malware during a scan.
Despite its name, F-Secure Online Scanner is a Windows executable downloaded from the product page. It is intended for checking and cleaning the machine, rather than submitting a website for analysis. Read the current preparation instructions before running it: the reviewed page asks for other antivirus programs to be uninstalled first. That makes this a planned remediation step with a clear way to restore continuing protection afterward, not an action to improvise in the middle of normal work.
