A couple Limewire questions...?

Okay, last time I installed Limewire, it started uploading everything on my computer... WTF? Why did it do that? Was it supposed to? If I try to install Limewire again, and it does it again, how would I stop it?

Second question, would Avast! (a freeware antivirus program) protect against most of the viruses in the programs, or is it completely useless?

Limewire is NOT a website, it is P2P. You download "stuff" from other Limewire users personial computers, while you upload your "stuff" to theirs. Thats how P2P file-sharing works.

And NO anti-virus can ever be relied upon to give 100% protection. None of them do, even the best. And while Avast is good, it is by no means the best. Most only detect about 85 to 95% of all KNOWN viruses. When a brand new virus is released , NO signature-based anti-virus will detect it for several hours up to several days. And over 1200 new variants of viruses and other malware are created by the "black-hats" each and every day.
