× Few antiviral products inadequately detect 3proxy as Trojan.Daemonize, Backdoor.Daemonize, etc and many detect 3proxy as a PUA (potentially unwanted program). It may cause browser warning on download page. 3proxy is not trojan or backdoor and contains no functionality except described in documentation. Clear explanation of this fact is given, for example, in Microsoft's article.

3proxy TransparentPlugin plugin (Linux/BSD only)

Plugin can turn 3proxy into transparent proxy for virtually any TCP-based protocol and use all 3proxy features - redirections, parent proxies, ACLs, traffic limitations, etc. TransparentPlugin plugin takes destination IP:port from Linux and uses this information as a target IP in proxy. An example of usage:
plugin /path/to/TransparentPlugin.ld.so transparent_plugin
log /path/to/log
auth iponly
allow * * * 80
parent 1000 http 0.0.0.0 0
allow *
parent 1000 socks5 SOCKS5_IP SOCKS5_PORT USER PASSWORD
transparent
tcppm -iLOCAL_IP 12345 127.0.0.1 11111
notransparent
proxy
Now, any TCP traffic transparently redirected to port 12345 will be routed via parent SOCKSv5 proxy and logged, all URLs for web requests are visible in logs. Paremeters '127.0.0.1 11111' in this case are not used and are overwritten by destination IP:port for each transparent connection.
