If your spyware detects LW as having spyware then it is a false-positive. The answer is to put LW on the exceptions list. And no, LW does not have spyware. I've had discussions with the owner/admin of the spyware forums ... & that's a good place to find reports of decent spywares or bad reports. Their main 2 recommendations are 1.
ad-ware (FREE), & also this one 2.
Spybot - Search & Destroy (FREE)
We did have a discussion over one they recommended but which gave false-positives to both LW & another p2p program due to it not being properly configured for p2p use.
