Abstract
Embodiments are described for removing malicious code from a file in a first file format by converting the file into a converted file of a second file format. In embodiments, converting the file eliminates malicious code embedded within the file from being stored in the converted file. The conversion is performed within a restricted computer process that has restricted privileges limiting its access to an operating system and an underlying computer system. As a result, even if malicious code embedded within the file executes while the file is being converted into the converted file, the damage to a computer system is mitigated because of the limited privileges provided to the restricted process.
