Gnutella Forums - Need Help new to LW

Ok so i just got limewire and have heard great things about it. So far it hasnt been a good experience, maybe some one could help. First off, a folder called "Complete" keeps reappearing full of weird porn .zip files. And i dont know how to stop that, it reappears everytime. Is there a way to stop this? Next, whats really annoying is LW keeps opening by itself. Right now i have selected in options to shut down immediately. No luck, it keeps reopening. I close it in the system tray and chose exit, after about 10 sec, it reopens. Am i missing something here, i havent used P2Ps in awhile. I want to beable to complete close the app, is there a way to do that? Furthermore, i just left it on overnight and like 10 instances of LW were shown in my system tray, even though there was only one instance actually running. I dont know what to do, its pretty weird. Some help would be appreciated. thx
