Date updated: December 24, 2024
The efw file extension is used for a compressed ZIP or executable EXE file renamed by CA Security Centre.
Typically applies to e-mail attachments scanned by Computer Associates (CA) antivirus software.
EFW zipped files may be opened by changing the file extension to .zip and opening the file with a decompression utility, such as WinZip. Executable files may be run directly by changing the file extension to .exe and opening the file.
Probably cannot be converted to anything else.
