Archives and compressed files

The library has a built-in support for the following formats:

• Zip
• RAR (2.0)
• Tar
• Gzip
• Bzip2
• MS OLE2
• MS Cabinet Files
• MS CHM (Compiled HTML)
• MS SZDD compression format
• UPX (all versions)
• FSG (1.3, 1.31, 1.33, 2.0)
• Petite (2.x)

Due to license issues, support for RAR 3.0 archives is currently not available in libclamav (such archives will trigger the RAR module failure. error message). You can scan them with the help of external unpackers in clamscan, though.

	$ clamscan --unrar clam-error.rar
