I just started using Limewire (V4.12.4). My downloading is going fine so far but then Avast starts detecting TROJANs on all these files that i havent downloaded or even searched for! Also, its finding them in a folder within my `downloads` folder that i can`t see. I tried searching the folder for the files as they come up but nothing. WHAT are these things? Where did they come from and how do i stop them getting in all the time?

Please help..
Thanks
