Can't fix "FO - system.ini: Shell=" with HJT

Hi,

I have run all the "Read and run me first" list and have resorted to HJT. As long as I have the tutorial by my side, I am okay with that. But the tutorial says to fix any "F0's" because the are "always bad", but for some reason, I can't fix this one. It always comes right back up when I rescan.

Oneother problem is that I have:

010 - Unknown file in Winsock LSP: c:\program files\bonjour\mdnsnsp.dll

The tutorial tells me to fix these using LSPFix or Spybot S&D. I tried to run the LSPfix, but it was a bit confusing to me and nothing, I don't think, came up on it, anyway. Everything that came up was listed on the "keep" side. I've had Spybot S&D and run it periodically, anyway, so I updated and ran it as well, but it comes up empty, too. Is there something I have to do to tweak it , or something?

Thanks for any help you can give.
