clamav-freshclam 0.91.1-1ubuntu3 (amd64 binary) in ubuntu gutsy

 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 program freshclam and scripts to automate virus
 database updating. Depends on an internet connection to function, but can be
 run in a variety of ways to compensate for intermittent connections.
