Bytecode Analysis and Testing Tool

## NAME

clambc - Bytecode Analysis and Testing Tool

## SYNOPSIS

clambc \<file\> \[function\] \[param1 ...\]

## DESCRIPTION

Bytecode signatures are a platform independent executable plugin format that extend ClamAV's malware detection capabilities. This tool is provided for signature authors and ClamAV developers to test bytecode signatures and bytecode runtime performance. \*\*Caution\*\*: You should NEVER run bytecode signatures from untrusted sources. Doing so may result in arbitrary code execution.
