I'm having a bit of trouble sending an MP3 to a friend...
the file is http:// freespace.virgin.net/geo.neil/gunther-ding_dong_song.mp3
Firstly, I downloaded the tune through Shareaza and contacted them through MSN using Gaim, they weren't around so I uploaded it to my webspace on virgin.net with no problems (I'm aware that virgin.net have AV on their e-mail, unsure about their webspace FTP server)
When I posted the link to my friend on MSN, her PC apparently crashed.
When I sent her the file using the offical client, her PC apparently said the file was harmful. (this warning apparently came from Windows itself and her AV program)
She's using McAfee Anti-Virus. She didn't note a name of the virus or trojan stored on the file, she apparently normally has no problems playing or downloading MP3s in this way, just with the file I sent her.
I haven't tried sending the link or the file to anyone else and am currently running a full scan on my PC using Avast (virgin.net customer services has suggested that viruses can sneak their way into JPG files, I didn't ask if their webspace FTP server filters viruses like their e-mail servers apparently do but the file did upload OK)
I'd also like to point out that the file plays fine in the following programs...
Firefox 1.0 through the Quicktime plugin
Media Player Classic (unsure of the version)
Haven't tried it in Winamp yet and as for IE and Windows Nedia Player (what I'm guessing she's using> ...I'll get back to you about that.
