clamav 0.90.2-0ubuntu1 (amd64 binary) in ubuntu feisty

 Clam AntiVirus is an anti-virus toolkit for Unix. The main purpose of this
 software is the integration with mail servers (attachment scanning). The
 package provides a flexible and scalable multi-threaded daemon in the
 clamav-daemon package, a commandline scanner in the clamav package, and a tool
 for automatic updating via Internet through the clamav-freshclam package. The
 programs are based on libclamav2, which you can use in your own software.
 .
 This package contains the command line interface. It has:
   * built-in support for RAR (2.0), Zip, Gzip, Bzip2, Tar, MS OLE2, MS Cabinet
     files, MS CHM (Compressed HTML), MS SZDD
   * built-in support for mbox, Maildir and raw mail files
   * built-in support for Portable Executable files compressed with UPX, FSG,
     and Petite
 .
 For scanning to work you'll need a virus database. You have 2 alternatives:
  * clamav-freshclam: updates the database from Internet. This is
    recommended if you have Internet access.
  * clamav-data: for users without Internet access. Isn't updated at all
    once it's installed. You can easily create your own updated package from
    an Internet connected computer however, using clamav-getfiles.
