Free Malware Scanners for Windows That Catch Threats | 2

The Microsoft Safety Scanner is a blunt emergency tool, not a full-time protection suite. I’d reach for it when a machine is already compromised and you need a free way to identify or isolate the threat before trying other repairs.

HouseCall is a straightforward way to clean a Windows machine when you suspect a virus and do not want to commit to a full-time security suite. It suits one-off checks well, but it is not built for ongoing firewall, VPN, or parental-control coverage.

The strongest part of Roboscan Internet Security Free is its broad, free protection set, with real-time defense, multiple scan depths, a basic firewall and a file shredder. I’d trust it for baseline security on a home PC, but the lack of automatic updates and the limited firewall mean heavier-duty protection needs a more complete suite.
