I've got the same problem. It started after I download a "supposed" photoshop filter pack. I unpacked the .rar file and the setup.exe file installed something that is causing this issue. I had over 12,000 files shared. It is sharing them from the c:\\windows\fonts\'\ file but that folder isn't even visible. I've went directly to that filename and deleted all of the files (a bunch of 113kb .rar files with different program names) and it will always reinstall all of these files on my computer in the same location. It also doesn't allow me to shut off limewire or edit any settings. If I shut down limewire, it starts it back up within a few minutes. I've deleted limewire 4 different times and reinstalled various versions and it's helped nothing. The latest install showed this error box message:

STARTUP ERROR!

I have no idea what it means but hopefully somebody does and can fix this problem. It's obvious that someone is exploiting the limewire system to force people to share their "virus" programs without meaning to. I'm about ready to lose my mind over this crap.
