I just found LIME WIRE and I think is amazing, now I want to install it on my job but I want to know what kind of risk I could afront if I do this, ( virus, hackers, etc ), and how can I under cover lime wire of the network administration.
Can so body give any info about this ?

Check with your work admins what to do. Work networks often need to have special security, so see if they think this is a good idea.

for sure, the admin and my boss wont be happy if use LI on the office, because I should be working not downloading music. But sometimes I have free time, so I want to grow my mp3 collection, but I dont want that this gays notice this.
