What's Winamp?
MP3 player, at this time
used by about 1/2 of mp3 listeners.
In case you don't know what a skin
is -- short: it's a set of images and instructions that make your
Winamp look the way it looks. All these images may or may not be zipped
in a .zip or .wsz file. They can also be in a separate
subdirectory of your Winamp skin directory. In no way can a skin itself
harm your computer unless in a very strange situation (say you would
try to install a skin on an almost out of space disk or something...)
