W32.Sobig.F Cleaner

W32.Sobig.F Cleaner is a lightweight piece of software designed to identify and remove files infected with the Sobig malware agent.

This used to be both a worm and a Trojan horse, and the Sobig.F variant used to affect machines via email, but it deactivated itself many years ago. Even so, you can use this program if you suspect your PC to contain remnants of the threat.

There is no setup pack involved. Instead, the entire tool's wrapped in a single executable file that you can save anywhere on the disk or copy to a removable storage unit, in order to directly run it on any PC to check for malware. It doesn't need DLLs or other components to work properly, nor does it add new entries to the system registry.

When it comes to the interface, W32.Sobig.F Cleaner opts for a standard window with a simple design and layout, revealing all options put at your disposal. It can be instructed to scan all fixed drives or just a particular one from the computer.

The tool looks into all known locations for the Sobig infection, populating a list with all files as soon as they're identified. It gives you the possibility to select the ones you want to clean, while sparing the rest. System restart is necessary to complete the operation if the files are currently being used by the computer.

It worked smoothly in our evaluation, without hanging, crashing or prompting errors. CPU and RAM usage was minimal, so it didn't affect the overall performance of the machine. However, you should keep in mind that W32.Sobig.F Cleaner doesn't offer real-time protection from malware, so you should download and install an antivirus solution equipped with this component.
