Hi Spectrum,
If you downloaded LW from the official site
www.limewire.com then it will have no ad/spyware. A scam version may be a different story! Some programs will detect LW as adware, it's a false positive.
Do some research... search the forum (top right, between faq & home). Look for "adware in limewire" or something similar. Here's one thread, there are heaps more
