The cfxxe file extension has been associated with executable files used by some malware programs. There is no reliable public information describing a standard file format.
On Microsoft Windows, Avast Antivirus and Ad-Aware PRO can be used to examine files associated with this extension. The format should be treated as potentially dangerous rather than as part of a known software package.
Do not open a cfxxe file manually. On Microsoft Windows, scan it with Avast Antivirus or Ad-Aware PRO, and follow the program's instructions to quarantine or remove it if it is detected as malware.
A potentially malicious executable should not be converted. There is no known legitimate conversion tool for the cfxxe file; use antivirus software to analyze, quarantine, or remove it instead.
