ABSTRACT:
Techniques and apparatuses for scanning a computing device for malware are described. In one implementation, a trusted operating environment, which includes a trusted operating system and a trusted antivirus tool, is embodied on a removable data storage medium. A computing device is then booted from the removable data storage medium using the trusted operating system. The trusted antivirus tool searches the computing device for malware definition updates (e.g., virus signature updates) and uses the trusted operating system to scan the computing device for malware. In another implementation, a computing device is booting from a trusted operating system on a removable device and a trusted antivirus tool on the removable device scans the computing device for malware. The removable device can update its own internal components (e.g., virus signatures and antivirus tool) by searching the computing device or a remote resource for updates and authenticating any updates that are located.
