AutoSandBox - FLAC for Windows

Hi, this morning I downloaded FLAC (Free Lossless Audio Codec) for Windows from:
http://flac.sourceforge.net/download.html
http://downloads.sourceforge.net/flac/flac-1.2.1b.exe

When I tried to install flac-1.2.1b.exe, I got an alert from Avast AutoSandBox. I got a similar alert when I used the software to decode a FLAC file and, again, when I unistalled the program.

Each time I chose to regularly execute the command, but now I have a doubt: is FLAC for Windows really secure?

Masculo

Note: Windows XP SP3 + Avast 6.0.1125 (virus defs update 13.06.2011)

The only way to get more info would be submiting the file to www.virustotal.com and posting back…

Done!

Well… Seems a false positive, doesn’t it?

Should I worry?

I don’t think so…

Many thanks!

Have a nice day!
