dose it just keep coming up every time you start the computer? like you start the computer ,LW pops up , you close it and you don t see it agen till you turn off and then start up the computer agen? if that is the case you just have it set wrong and you have no virus problems. if it just keeps bombarding you agen and agen with itself after you try to close it many times ,you prolly do have a virus, or you have a "bad" copy of lime wire (if you downloaded it from a scam/spoof site or via p2p this could be your problem.
