All my songs in my Limewire libary will not now play, they all have the Windows logo to the left of song title, they have all changed to exe and are all now the same length. I can still download new songs (i have now saved them to disc straight after downloading) but when i switch Limewire back on, the recently downloaded songs have changed to exe,windows logo etc. Ive scan my Pc and any harmful things removed but still this happens. Anyone experiencing the same?

If your files have changed to .exe, I bet you're infected. Check the threads below for a bit more info

Apparently AVG picks this thing up (hopefully all AVs will do by now). Download AVG free, update it & scan...see if it finds a worm delf.ATB...let us know how you go.
