AFAIK there are no known mac OSX viruses. So nothing to worry about there. And windows viruses don't affect mac. But I try to be careful not to downld windows viruses anyway & do keep an AV program handy to scan files in any case so I don't pass any viruses on. 99% of the virus definitions for my AV program are for windows & the other for mac os 9 & earlier.

Don't forget to describe your files properly & meaningfully. You can do that with an id3 tag program or use LW's describe function. The best mp3 tagger for mac is Media Rage. Send my a personal message by clicking on my username & I can describe more about it. A well described file will make it easier to find in a search on the gnutella network.

If there's anything in your LW Library you don't want to share, then control-click the file or folder & choose stop sharing.
