## What it is
avcleaner is a C/C++ source-to-source obfuscator built on LLVM, designed to evade antivirus detection by transforming source code (e.g., hiding strings and API calls). It is a compiler-frontend-based CLI tool primarily aimed at red team and security research use cases.

## Use cases
- obfuscate C/C++ source code to bypass antivirus detection
- hide strings in malware-like tooling during red team engagements
- evade static signature-based scanning of security tooling
- learn LLVM-based source transformation techniques
- transform Windows C/C++ projects that use the WinSDK

## When to choose
- you are a red teamer or security researcher needing to evade AV static analysis of your C/C++ tooling
- you want an LLVM-based source obfuscator you can extend or study
- you need to obfuscate strings and sensitive constructs at the source level before compilation

## When to avoid
- you need a general-purpose code obfuscator for protecting commercial software IP
- you require support for languages other than C/C++
- you need a maintained tool with frequent updates and broad platform support
- obfuscating code would violate laws or organizational policies in your context
