I didn't think Mac users had the same problems with viruses that Windows users have. Do you realise that you posted onto a Mac thread?

Just in case you aren't even a Mac user... the download page has a link "About Using p2p Software Safely": Lime Wire » About Using P2P Software Safely
You should have read that info. Did you do any research at all, before you started using LW??? It's p2p - there's no control over what's shared. It's up to the user to protect themselves.

You should have tried the free basic LW first. Then you wouldn't be wanting a refund Use the forum search to look for virus - maybe you'll find some info to help.

Next time, be a bit smart. Make sure that you're using a good AV program. Keep it updated & use it to scan all files that you download - before you open them
