Backdoor.Daemonize, etc and many detect 3proxy as a PUA (potentially unwanted program).

You can use every proxy as a standalone program (socks, proxy, tcppm,
udppm, pop3p) or use combined program (3proxy). Combined proxy
additionally supports features like access control, bandwidth limiting,
limiting daily/weekly/monthly traffic amount,
proxy chaining, log rotation, syslog and ODBC logging, etc.
It's created to be small, simple and yet very functional.
It may be compiled with Visual C or gcc. Native Win32/Win64 versions included
in archive and supports installation as a service. Currently
3proxy is tested to work under Windows since 98 (Windows before Vista reqires lite version) and up to latest version both i386 and x64,
FreeBSD/i386/x64, NetBSD/i386/x64, OpenBSD/i386/x64, Linux/i386/x64/PPC/Alpha/arm, Mac OS X, Solaris/i386/x64.
