I am not sure what category to post this problem in so I apologize in advance if this is not the correct area and thank you for moving it.

Here is my problem. This is a Dell XPS studio desktop I am having trouble with running windows 7. Certain websites do not work and some do just on this computer. I have 4 others on this network and they all work fine. Some sites that arent working are Netflix, Dell, Marketwatch. Some examples of site that are working fine. Tomshardware, yahoo, google. I have tried multiple browsers including firfox, IE and Chrome and the results are the same regardless of the browser i try. This is the error message I get when trying to connect to one of these sites:

Unable to connect

Firefox can't establish a connection to the server at www.marketwatch.com.

* The site could be temporarily unavailable or too busy. Try again in a few
moments.

* If you are unable to load any pages, check your computer's network
connection.

* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.

Also note that I tried to visit these troubled sites using PROXIFY and they loaded fine when using proxy server. Does anybody have any idea? I reloaded network driver, rolled back windows to 2 months ago although I am not certain when it started and tried reinstalling the browsers. Thanks

Have you checked your security setting in Internet options? If they are set too high they may block content or certain sites from loading. Normally you want them set to default.

Next step is to check for viruses. A few things to check first is such as the host file. Its locatd at c:\windows\system32\drivers\etc. Open it with Notepad. there should be nothing listed after th example. If there is, delete it and save.

Then downloda and install CCleaner. Run it to kill out anything in the temp files. Then download and install Malwarebytes, Super Anti-Spyware and Microsoft Security Essentials. Run them all after installing and updating.

Hopefully if there is anything blocking your internet then it will get them.
