My guess is they are fakes. Beware of Fake files in search results

However if a virus, then try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.)

Could also Tip: Purge the Downloads Queue! (click on blue link)

nah they're definitely not fakes. once one of the three files has finished downloading, the next starts up and downloads fine. all the files are full and intact once complete.

i've tried deleting the preferences folder. no luck tho.

it says on that downloads page 5000 files. i've only got a dozen in there! i don't download all that much, but i went through and deleted what i didn't need. not much has changed
