Overview:
DoesNotBelong is a lightweight and specialized program for additional system scanning that compliments the main antivirus. It helps to identify threats not detected by the main antivirus and may be useful if you suspect an infection despite a “clean” scan result from other scanners.
The name, DoesNotBelong, comes from its ability to find and remove files in locations where files do not belong. For example, we wouldn’t expect to find executable files in the ‘My Pictures’ folder.
How to run a scan on your computer:
- Download DoesNotBelong.exe to your Desktop.
- Right-mouse click the saved file and select ‘Run as administrator’ to begin the scan.
- It is recommended to temporarily disable your antivirus software so it does not interfere with the scanner. Watch this video if you’d like to understand more of why sometimes antivirus detects unknown, new, or rarely downloaded software.
- Review the report which is created when the scan is complete. The log file can be found on your desktop or at C: That’s it! The tool removes itself after execution, which is also part of maintaining a clean PC so you don’t have to waste time trying to uninstalling or deleting it afterwards
- Screenshots and video demonstrations available:
