Can someone explain what this Trojan Spreader is, exactly? I found that once I had it, a large portion of my music files duplicated two times in my Itunes. I didn't even check the folder where the original files are stored. Anyway, now it is almost impossible to download any more files. I've tried adjusting all sorts of settings, but just can't seem to get back to my quick and excellent downloading capability. Is there some culprit file I should be looking for to delete?

By the way, who would be such a freak to create a Trojan Spreader?
