Windows 7 home premium 64 Bit, updates are up to date. IE 11 Chrome (latest) Although uninstalled now. Firefox (latest) 26
Summary: Browse by name or IP address do not work. Cannot hit any website in any browser. No direct error. Just no response.
Details: System was hit with some form of redirect malware, not sure which one it was pretty obvious he had one though because when he would search within google, silly ads would pop up in Chrome. Eventually he called and said all internet had stopped working, not just annoying ads anymore. I went to work and cleaned up all the malware, or at least I think I have it mostly gone. All the latest scanners report nothing, Kapersky, GMER, hijackthis and so on.
From the command prompt system can ping and resolve any domain name you throw at it.
Machine has two NICs one wired, one wireless both operate the same.
Windows firewall has been disabled. Although I suspect it might be the source of the problem.
It appears that something in the OS is not allowing the communications out.
Fiddler doesn't show anything. I see the get request and no response.
Even tried two different ISPs.
Checked protocol default settings and protocols appear to be correct.
Proxies are turned off.
Uninstalled and re-installed all browsers
Uninstalled all virus scanners and known programs that interfere with network stack, like WinPCAP etc. No change.
Windows Update continues to work.
Any ideas where I should look next?
