I installed the vidalia package from http://tor.amorphis.eu/docs/tor-doc-windows.html.en, and as far as I can tell, that caused the problem. Now that i've removed it, I can no longer access any ssl (https://) websites from IE7.
Firefox works fine, but Safari Windows doesn't (as it uses the same security/connection settings as IE, I believe)
Normal websites work fine, but I get a connection error every time I try an SSL site, and my Event Viewer throws an Schannel error, "A fatal error occurred while creating an SSL client credential." (Event ID 36871)
Again, I'm fairly certain that Tor or Vidalia or Privoxy hosed some settings on my machine, or installed something malicious. Using
"netsh winsock reset" and
"netsh int ip reset" wouldn't fix it, so it's gotta be something deeper.
I'm attaching a Hijack This log, please help me get to the bottom of this!
