While trying to ftp some files through a proxy, I reached for my old friend Filezilla and downloaded a copy to my new windows 7 box.
Afterwards my browsers' home pages and search engines changed - arrrrrgggggghhhhhhh!!!!! - unanticipated adware choking my machine.
After an hour or so of trying to remove the adware - scanning, rebooting, scanning, rebooting - it was almost gone. That was an expensive "free" program. Oddly enough it loaded the Adware but not Filezilla.
After a wee bit of research, I downloaded WinSCP to ftp through a proxy. WinSCP read my putty settings and automagically loaded ftp sites. It works like a charm without the AdWare bloat.
