This woman wanted parental controls on her granddaughter's laptop (Win 7 x64, was a christmas present, mcafee installed and working). I went the opendns route for the parental control, and everything was great except that they had installed some sketchy looking "Action Alert Internet Parenting" junk (note, this isn't the dongle you'll see in searches for that, it's just a piece of software). Grandma had managed not only to forget the password for it, but had supplied an incorrect email address, making it impossible to do anything about the password. I ended up removing it by knocking out its main registry entries, then reinstalling it with a new password and doing a proper uninstall.
So what I have now is a situation where DNS doesn't work, specifically in the browser(s). I know the action alert junk had an LSP installed... it's no longer there, and I would think that netsh winsock reset should've fixed a problem of that sort anyway. Here's what I've done, and this is on my home network I'm speaking to you from, so it's not a network/internet issue.
Symptom: Cannot visit any website in a browser (tried firefox and IE, chrome won't install b/c the stub they give you can't find a source).
-- DNS *does* work. I can ping google, and ftp to ftp.mozilla.org from the command line. McAfee software is able to update itself with no problem, and windows update works fine.
-- The browsers *do* work. I can take the IP I get from pinging google and put it in the browser and search google just fine.
So of course I've been all over the internet on this, tried about a million things, including but not limited to:
-- ipconfig /flushdns
-- net start/stop dns
-- netsh winsock reset
-- netsh int ip reset
-- I've scanned it for anything malicious (mbam, mcafee)
-- uninstalled toolbars
-- switched DNS servers (isp, opendns, google)
-- multiple browsers
I've been over internet options with a fine toothed comb, dug through HJT logs for internet explorer modifications, pretty much done everything I've learned from years of removing viruses and other filth, and I've got nothing. It's utterly infuriating to be looking at a reinstall to fix a 3 month old computer that hasn't even been infected yet.
Any help would be greatly appreciated.
