Any filesharing program will enable you to download either a virus or a program containing a virus, use common sense and use a good Anti-virus program and keep it updated. Scan any downloads before running them .
It's less of a problems with music files but some are names as
"song name.mp3.vbs" and are very small in size and are usually worms or trojans.
Use common sense.
One more thing,
I've used iMesh-lite in the past too and while Kazaa lite is in my opinion a far better P2P file sharing tool, iMesh does offer the ability to automatically scan for viruses.You will have to point to your anti-virus program by entering something like the following without quotations
"Crogram FilesNorton AntiVirusNAVAPW32.EXE" in the settings.
I'm not too sure on the current availibility of iMesh-lite.
