I've gotten to the point that my dev machine does not connect to *anything* except my sites and my AV and malware updates. I do deep scans before firing up FTP or Frontpage. The machine is not networked with any other. Heck, I even disconnect the ethernet cable when not in use.
I do all my ftp etc from a Mac and only use my PC for research and never log into any sites from the later that would compromise the former (my pc has AV and Malware running). It's also not connected to the Mac other than the router. I hope that's safe enough.
