I'm new to limewire and didn't realise this about zip files, thanks (patty80 is right, it is deceiving given the number of users that are sharing them - though I suppose that is part of the strategy)

Just to check - I did unzip one that I downloaded and ended up with 3 .exe files. I have since trashed the lot, but I am on a mac so I shouldn't have any problems anyway right? (as they are exe files, plus I didn't attempt to run them)
