clamav-testfiles 0.88.2-1ubuntu1 (i386 binary) in ubuntu dapper

 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 libclamav1, which you can use in your own software.
 .
 This package contains files 'infected' with a test signature. The test
 signature (ClamAV-Test-Signature) should be detectable by all Debian
 Antivirus programs.
