I am building ClamAV from the original sources, to make freely available my optimized compiles. I am not modifying original code, but applying a different build chain to gather a better executables, in terms of native x64 support as well as regular x86; faster execution speed; smaller executable size; and lower memory footprint. Of course, the rest of features, should be exactly the same as in official ClamAV.

To prevent any possible confusion, my releases are groupped under the ClamAVOpt name, as an acronym of "ClamAV x86/x64 Optimized Builds".
