Fake? Not sure how that happened, as I downloaded it directly from Bearshare.com

I guess I'll try an older version - as I only temporarily fixed the problem. I uninstalled BS - and manually deleted anything bearshare on my PC. Reinstalling BS (version 7) worked fine.......only for a couple days.
Now, my Firefox homepage has been changed (without my prompting) to search.bearshare.com

Very frustrating - and the bozo's over at Bearshare don't seem to know what could be causing this (or are just playing dumb).
