Windows 7 can't browse the web

A couple weeks ago, my Windows 7 machine became unable to browse the web. I have three browsers (IE8, Firefox, Chrome) and they all exhibit the same basic symptoms - when I put in a URL and press Enter, I get nothing back. In Firefox, there is just a blank page. In IE8 I get the "page cannot be displayed" error. In Chrome, I get "This webpage is not available", and the associated error message is "Error 105 (net::ERR_NAME_NOT_RESOLVED): The server could not be found"

- The only internet connectivity I have is public WiFi. I am able to pull an IP address from DHCP. I am able to ping the default gateway, do Traceroute to common sites (CNN, Google, etc, etc) and NSLookup verifies that my DNS is working without any apparent issue.
- I have tried reinstalling my Wireless drivers
- I am not going through a Proxy. I verified that IE8 and Firefox are not configured to go through a Proxy.
- I tried uninstalling all antivirus software (Norton) and disabling Windows Firewall, no change
- I have reinstalled Norton, as well as Malwarebytes and SuperAntiSpyware, but they are not finding any apparent malware
- I was able to get to the web using a pre-installed utility called "Sony Update" which is an .exe that launches IE and points it at a specific website in the sony.com domain. Using this browser session, I'm able to surf to anywhere.
- I was able to restore what appears to be full functionality by using a Restore Point to a time before the issue started happening. However, the next time the computer is restarted the problem re-appears.
- Also in Device Manager, I am seeing two devices under Disk Drives that as far as I know, have never been on this machine - there is "Ricoh Memory Stick Disk Device" and "Ricoh SD/MMC Disk Device". Neither of these are showing up under My Computer.
- I am also seeing occasional hangs or crashes in IE8 and Firefox

Despite the malware scans you have run, it appears you have some deep-seated rootkit type of malware on the machine. I think the biggest evidence of this is that a restore to a prior point works, and then restart allows the rootkit to re-establish itself and kill your internet.

You can try a rootkit revealer to see (System Internals / Microsoft), but my guess at this point is that you are looking at re-installing your OS (as unpalletable as that is). ... Thinkpads_User

I have a question for you,

If you can remember, when was the last time this configuration worked?

Was something added or changed right before your computer became unwell?

The apparent catalyst to this problem might have been a collection of MP4 and Acrobat files that I copied to my C drive, which were contained in a ZIP file. I scanned it all with up to date antivirus signature before opening. My PC was pretty much up to date with the latest Windows updates. The only one that I possibly didnt have at the time was KB977863 (Cumulative Update for Media Center for Windows 7 x64 based systems) however there is no mention of any security updates included in that patch.

I suggest that you follow thinkpads_user's suggestion. Get yourself a copy of rootkit revealer and give that a go.

You could also try Combofix.

Rootkit Revealer is apparently only compatible with Windows XP.
So far, I have tried anit-rootkit tools from Sophos, Avast and SanityCheck. Nothing signifigant showed up. I'm in the process of getting ahold of Combofix.

Combofix is available here:
http://www.combofix.org/download.php

Maybe you should also disable all browser add-ins and see if that fixes your problem.

Combofix is apparently not compatible with Windows 7. I am getting a message to that effect when I tried to install the software.

I have tried running IE8 and Firefox with the no add-on options, still the same issue.
