ClamAV Antivirus Native Win32 Port - 1.4.2-r1
This is an unofficial native port of the well-known ClamAV Antivirus. This port is used in ClamWin Antivirus.
Available Versions - 1.4.2-r1
- clamav-1.4.2-r1-x64.7z (64-bit): Built with Visual Studio 2022. Compatible with Windows 10 and later. Includes LLVM JIT support.
- clamav-1.4.2-r1-winxp-x64.7z (32-bit): Built with MinGW-w64. Compatible with Windows XP and later. Uses a custom compatibility layer (Beta quality).
- clamav-1.4.2-r1-winxp-x86.7z (64-bit): Built with MinGW-w64. Compatible with Windows XP and later. Uses a custom compatibility layer (Beta quality).
Notes
- The registry key for config directory is changed from ConfigDir to ConfDir.
- x64 package is built with Visual Studio 2022 and needs Microsoft Visual C++ Redistributable for x64.
- The Windows XP-compatible versions rely on a custom compatibility layer, making them experimental and beta quality.
- The 32-bit version may struggle with the current size of the ClamAV signature database, especially when performing a clamd reload.
- If you're still using Windows 98 or Windows NT 4, you can download the previous 0.103.12 version here.
- On Windows NT 4, you may need to set the
OPENSSL_ia32capenvironment variable to~0x1000000as NT4 does not support SSE (to avoid an illegal instruction error).
Source Code
The source code is available on GitHub.
I spent many sleepless nights creating and debugging the Windows XP compatibility layer. If you appreciate this effort, please consider donating.
