Unblock any website using Google proxy server

I already wrote a topic how to open a blocked website by hiding IP address. For that process you needed to install a software which will use a proxy address and hide your IP address.

Today I will show you how to open any blocked website without any software. You will hear about so many proxy server. But when you goes to try that proxy server you will see most of them are blocked from your school, college or workplace server. Now the question is how I access those website? Is there any other method?

No. I am not talking about any new method. I also use proxy server, but this proxy server will not be blocked by your school, college or workplace administrator. Though they know about this tricks but they do not want to block this proxy server. I am going to tell you that how to use Google as a proxy server. And I am sure any administrator do not want to block Google. Because it is the most popular search engine.

When you access any page via one of these Google proxies, the content of that page gets downloaded on Google servers and then served to you. Let us discuss how to use Google as a proxy server. Here I will show three method.

  1. Google Translate as a Proxy.
  2. Google Mobilizer as a Proxy.
  3. Google Modules as a Proxy.
Google Proxy Server

Google Translate as a Proxy

To use Google Translate as a proxy, set the destination language as the actual language of the page and the source language as anything but the destination language.

For instance, if you are to access a page written in English, set the destination language (tl) in the translate URL as “en” and the source language (sl) as “ja” for Japanese. (example)

Advantage: This is the most popular Google proxy and the download web pages looks exactly like the original provided the domains serving the images and CSS are not blocked at your place.

Google Mobilizer as a Proxy

Next in the list is Google’s Mobilizer service. Google has discontinued the main mobilizer service on google.com (secure) but you can still access it through any country-specific Google domain like google.co.in or google.ie. The URL would be:
http://www.google.ie/gwt/x?u=http://example.com/ (example)

Advantage: The presentation (CSS) is not retained but this mode is perfect for reading text-heavy pages and do have the option of disabling inline images for faster loading.

Google Modules as a Proxy

The gmodules.com domain is part of the Google personalized homepage service and is primarily used for hosting gadgets that are available for the Google homepage.
http://www.gmodules.com/ig/proxy?url=http://example.com/ (example)

Advantage: This is the only Google proxy that will let you download files (like PDFs, .MP4 videos, etc) in addition to viewing regular web pages.

A better way to speed up of your PC

Is your computer slow? No matter how good you are about keeping your computer clean and up to date, all computers seem to slow down after time.

The causes of your computer being slow can include:
  • Not enough hard drive space, too many unused programs.
  • Left over programs, old cached and temporary files.
  • Too many programs running at startup or in the background
  • Data Corruption, hard disk fragmentation
  • Missing Windows updates or outdated drivers
Whatever the cause, there are lots of ways to help speed up your computer and make your PC work better—even without upgrading your hardware. This easy to follow, step by step guide will help to speed up your computer.

Background programs

One of the most common reasons for a slow computer are programs running in the background. Remove or disable any startup programs that automatically start each time the computer boots.

Tip: To see what programs are running in the background and how much memory and CPU they are using open Task Manager.  If you are running Windows 7 or higher run Resmon to get a better understanding of how your computer is being used.

Solution: In the Search programs and files box, type msconfig and click on the msconfig icon that appears. When the System Configuaration window appears, click on the Startup tab.  Then uncheck those programs you wish not to start and click Apply.

Free hard drive space

Verify that there is at least 200-500MB of free hard drive space. This available space allows the computer to have room for the swap file to increase in size as well as room for temporary files.

Bad, corrupted or fragmented hard drive

  • Run ScanDisk, chkdsk, or something equivalent to verify there is nothing physically wrong with the computer hard drive.
  • Run Disk Defragmenter to help ensure that data is arranged in the best possible order.
  • User other software tools to test the hard drive for any errors by looking at the SMART of the drive.

Update your drivers

  • Make sure you've got the latest drivers for your computer, especially the latest video drivers. Having out-of-date drivers can cause an assortment of issues.
  • If you are on the Internet when your computer is slow also make sure all browser plugins are up-to-date.
  • Make sure you have all the latest Windows updates installed in the computer.

Hard drive upgrade

One of the biggest bottlenecks of a computer is the hard disk drive. For anyone with a slow computer or just looking for something to upgrade in the computer to improve overall system performance going from a traditional HDD to a Solid State Drive (SSD) will significantly improve the overall system performance.

Do you have more than one antivirus program?

If you use more than one antivirus or anti-spyware program at the same time, your computer may experience decreased performance, become unstable, or restart unexpectedly.


  • When you remove your currently installed Internet security programs, your computer may be in an unprotected state. 
  • Make sure you have an Internet security program running on your computer at all times.
Tip: You will need to restart your computer while following these instructions. Write them down, print them, or bookmark this page (mark it as a Favorite) to make it easier to find this topic again.

Step to Remove antivirus or anti-spyware programs

  • In Windows XP, click Start, click Run, type appwiz.cpl, and then press Enter.
-OR- In Windows Vista, click Start. In the Start Search box, type appwiz.cpl, and then press Enter.
-OR- In Windows 7, click Start. In the Search programs and files box, type appwiz.cpl, and then press Enter.
-OR- In Windows 8, Swipe in from the right edge of the screen, tap or click Apps and then tap or click Search (or if you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click Search).Type appwiz.cpl in Search box, and tap Appwiz.cpl on the left side of your screen.

  • In the list of installed programs, uninstall any other Internet security programs.
  • Restart your computer.

  • Some Internet security applications do not uninstall completely. You may need to download and run a cleanup utility for your previous security application for it to be completely removed.
  • If you use another anti-spyware program together with Microsoft Security Essentials, we recommend that you turn off real-time scanning in the other program. For more information, see the documentation supplied by that anti-spyware program.
