Any time you use a Peer-2-Peer file sharing program, you must allow a "hole" into your system so the rest of the world can share files with you.. In addition, you are downloading files from "who knows who" on the internet.. As a result, what they give you is what you get.. "What you get" may be malware..
Hope this helps.
I have Windows XP Pro,sp2.
You can get and install LimeWire, but should you. It seems I read that LimeWire was a source of bad stuff for your computer.
I'd like to know what the consensus is. Please let me know.
