Internet Explorer cannot display the webpage, Google, Gmail, Youtube, Firefox home page, Live.com, Msn and possibly more sites more won't load

I suddenly just had this problem where Google.com, Google.ca Youtube.com, Youtube.ca, Live.com, Live.ca, Msn.com, Msn.ca and possibly more sites ( I just haven't tested each site out yet ) fail to load. The wierd thing is - these sites were all loading for me this afternoon and I haven't installed anything or deleted anything or changed anything since then.

It seems that everything that is related to Google will not load on my browser. I have tried 5 different browsers and this problem will not go away.

The address is not valid
   
   Most likely causes:
There might be a typing error in the address.
If you clicked on a link, it may be out of date.
 
   What you can try:
     Retype the address.  
 
     Go back to the previous page.  
---------------------------------------------------------

NOTE: Yahoo will load | Many other sites will load | I do have a firewall (password protected, forgot password) but I do not remember blocking google OR msn | I have already read about hosts file, and I have tried entering google.com + ip address - does not work.

PS google.co.uk works?!? but just not the others? could it be a problem with my ISP?

Soo yeah, this is really frustrating and scary at the same time.
If anyone could help me resolve this problem I'd appreciate it greatly!

Thanks,
Jason

First thing to figure out is whether it's your machine, or your ISP, or your ISP's DNS servers.  

Do you have another PC you could try, utilizing the same connection to determine whether it's a setting in your PC?

Alternatively (this is not QUITE as good), can you create a new user account on your existing PC, and try surfing to those sites from that account?  

To rule out your ISP's DNS servers, try manually setting your PC to use a different set of DNS servers - for example, those at opeDNS:  208.67.220.220 and 208.67.222.222

Alright, so I tested it out on another computer in the house. It seems like it might be a problem with my machine. Google.com works on the other computer.

As for ISP DNS server, I have no idea how you manually set the PC to use a different set of dns server.

However, it seems like it doesn't have anything to do with my ISP since the other computer will load the page.

Good, the problem is being narrowed down.

Since your other computer will load these pages, we know, as you say, that it's not your ISP.  So the next step is to determine whether it's DNS-related.  To find out, get the NUMERIC IP address for one of the problem sites.  You can do this by using the WORKING computer to ping one of the problem sites, by opening up a command prompt, and typing, for example:

ping www.google.com 

You'll get a numeric IP address, something like 208.67.219.230

Now, go to the problem-child machine, and, in your browser, enter http://208.67.219.230 (or whatever IP address your working machine gave you for google.)

If you get the google homepage, then the problem is DNS related, and we know where to go next.  If you don't, then it's more likely malware related.

Alright I did this and it lead me to Google English. However when I try to type anything in and press Search, it will lead me back to the same "Internet Explorer cannot display the webpage" page.

So it is sounding DNS-related.  If you go to
Control Panel/Network Connections, select your connection, and right-click on it, and choose Properties,
then select Internet Protocol TCP/IP, and click the Properties button, what do you see in the lower box, the one talking about DNS servers?

Go to advanced, and delete that 0.0.0.0 default gateway (by clicking the Remove button)  so that default gateway is blank, instead of zeroes.  That would pretty much be your problem, I think.

Also just to add, for some sites I visit it shows a really messed up page + images don't load.

For example if I go to Flickr.com, or search something on yahoo, the result is a web page without any order, like theres no stylesheet or something. It just shows a white page with alot of links instead of showing the nice background and link colors, font, etc. It started around the same time google started not to work, so are these two things perhaps related? Malware? Virus? ( probably not becuase I just scanned my computer, no virus found ) Spyware?

Sorry to say - but it didn't work. It still shows up with the internet explorer cannot be displayed

With your default gateway set to zeroes, I'm surprised that you're getting out on the net at all...It may be that all you're seeing is portions of webpages that are cached on your system, from previous visits.  See what happens when you get rid of those zeroes...

akahanCommented:
Then it's sounding like malware or spyware, or you're screwing yourself with over aggressive firewalling (like what Spybot or Zonealarm does sometimes).

1) first go to start | Run and type:
 ping yahoo.com
if you get a message like
Reply from 69.147.76.15: bytes=32 time=331ms TTL=42
it's ok with your connection and go to step 2.
otherwise check your modem, connection properties and other things and make sure your ISP doesn't have any problem.
2) Open Internet Explorer, go to Tools, manage add-Ons and disable any add-on which installed by third party vendors. clear your history and delete all the files, cookies and etc.
It may work.
ping yahoo.com

Open in new window

Hmm it says Request timed out.
You know what, this is what I'm going to do and I'll see if it works or not.

I'm going to 1) system restore and then 2) unplug/replug my modem.

I'll be back in a bit with the results.

@Majidhajal

I tried using 5 different browsers.. and none of them work. I think its something blocking my connection to these sites, but I can't access my firewall since I forgot my password to it.

If there's anyway to get rid of the password to the firewall I could check to see if it really is the firewall's problem.

PS IM USING COMMODO FIREWALL + WONT LET ME UNINSTALL WITHOUT PASSWORD / CHANGE ANYTHING OR EVEN ACCESS IT WITHOUT A PASSWORD ANYHELP

Ideally, you'd want to uninstall Commodo firewall.  If you can't, because of no password, will it let you REINSTALL it, and, in the process, use a new password?

To future users who may find this information helpful:

After an apparently successful malware cleaning session with Malwarebytes, I was still having the IE8 connection problem similar to (but not quite the same as) this post. In my case, I couldn't get to any websites, but I could ping from a command prompt with no problems. Also, no other PCs on my network were having connection problems. I performed the suggested "IE8 | Tools | Internet Options | Advanced | Reset | Reset" and that did not correct the problem. However, for reasons passing comprehension, doing a reset of IE8 DID NOT RESET THE PROXY SETTINGS. Looking in "IE8 | Tools | Internet Settings | Connections | LAN Settings" I saw that the "Use a proxy server... " box was still checked. My location does not use a proxy server. Clicking on the Advanced button, I saw that the HTTP Proxy address to use was 127.0.0.1. Of course, this is the localhost and will never produce web page results (just a final FU from the malware authors).
