False positive: Win32:Trojan-gen. {Other}

I think I have a false positive on a DLL.

File: hhhlpdll.dll (Size 77877, MD5 5cf6e675e6470e52b891882ad3dfa900)
From: HHProxy freeware (http://home.t-online.de/home/SOG-Luebeck/hhproxy_rel.exe)
Website: http://home.t-online.de/home/SOG-Luebeck/hhproxy.htm
False positive: Win32:Trojan-gen. {Other}

Version of Avast: Avast! 4.1 Home Edition, Build Oct2003 (4.1.289),
VPS File 18.11.2003, version 0310-12.

The file was confirmed clean by F-Prot and McAfee Scan.

By the way, thank you for providing this remarquable antivirus for free for private use. Very nice piece of work. I recommend it on my website.

Best regards,
