0 Stop Google.com To Redirect To Google.co.in or Your Country Domain | Navigate To Google.com From A Country Google domain

Trouble:
Many of my friends ask me this simple question sometimes here in India, when ever they type google.com in their browsers they always get redirected to the google.co.in or their country specific google website.

Normally they used to ask me what is difference in between google.com and google.co.in, and does this affect the searches they make on google and the search results which appear.

Here is how you can either stop google from redirecting to google country domain or navigate to google.com simply from your google country domain

Fix:
Google.co.in in the google’s Indian web site where as google.com is the US website, so you are being redirected to your country google domain so as to filter your search results and provide you better results more faster by accessing the data centers located in your country or as near possible

But this difference will be negligible till when you are searching something on google which is not country dependent, still if you don’t want google.com to redirect then type www.google.com/ncr in your browser address bar – ncr stands for No Country Redirect. You can save the above address as bookmark in your browser to open google.com always

Another way is to let google.com redirect to your country google domain and then click the link at the google page for your country which says Go to Google.com [ as shown in the image above ]

Trouble:
Sometimes a virus or some malicious script makes the hidden files and folders not visible even when it is explicitly enabled.
In this case even if the user enables the Show hidden files and folders in
Tools > Folder options > View menu, Hidden files and folder does not become visible.
Lets see how to fix it.

Fix:
First and foremost is the point that the user has enabled the Show hidden files and folder
1. Go to Tools > Folder options. This will show a folder options menu.
2. Go to View tab and select the option “Show hidden files and folder
The hidden files and folders are displayed by this method normally. But in case some virus or script is preventing the hidden files and folders from being visible, follow the below steps:
1. Go to your Start > Run, type regedit and press enter. This will open registry editor.
2. Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folde r\Hidden\SHOWALL

Updated on 9th FEB 2008:
Note:
DELETE the value CheckedValue in the right window if it already there and type is REG_SZ
Now create a new DWORD value again with the same name CheckedValue.
3. Double click the value called CheckedValue, and modify its data value (DWORD Value) to 1 (0×00000001) . Close registry editor after this.
Updated on 9th FEB 2008:
If still folder options is reverted back to don’t show hidden files and folders then it could be due to some virus still in action.
Navigate to the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden
NOHIDDEN

In the NOHIDDEN folder, select CheckedValue and set the value to 1
4. Go to Tools > Folder options. This will show a folder options menu.
5. Go to View tab and select the option “Show hidden files and folder
The above fix to the trouble came from one of our readers Chris under a virus post comment.
Thanks Chris.
Note: If above solution does not work for you, make sure to make your system completely virus free by updating your anti-virus and running a complete scan

Let’s see how can you remove write protection on your portable devices like pen drives, memory cards, iPod and other USB mass storage devices.
Fix:
Write Protection on any portable USB Device can be applied by the physical lock provided on the card adjuster or some times provided on the pen drives, so make sure to make your drive not write protected by moving the lock in right direction.
But even after moving the physical lock for write protection the problem can happen due to some virus action. This happens when some virus or script which applies the registry hack to make any drive write protect when connected to the computer, In that case follow the procedure below to remove write protection from your pen drive.
1. Open Start Menu >> Run, type regedit and press Enter, this will open the registry editor.
2. Navigate to the following path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

Note: If the registry key StorageDevicePolicies key does not exist, you will need to create it
Download this batch file called add.bat from here, and double click after download the key will be automatically added to registry.
3. Double click the key WriteProtect in the right pane and set the value to 0 in the Value Data Box and press OK button
disable-write-protection
4. Exit Registry, restart your computer and then again re-connect your USB pen drive on your computer. That is it, done.
In case you still find an issue, please leave a comment below.

Updated on 28th May 2009
After a lot of user comments telling that the above method does not work for them, we tell you another method which you can follow to solve the “Pen Drive is Write Protected” problem.
If the above method does not work for you, follow the below steps:
1. Copy all the important data from this drive to your computer because this method will format the drive and erase all the data on the pen drive.
2. Now download the Apacer Formatting Utility, Unzip this utility to a folder on your hard disk, preferably on a folder on desktop screen for easy access (Do Not Try To Save it on pen drive). Keep your pen drive plugged in, and double click on the Start.bat file in the folder where you unzipped the above utility. This will start formatting your pen drive, wait till the formatting completes and the LED on your pen drive stops blinking. Remove your pen drive after than and plug it in again.
The above two steps will solve the problem. If you still face the problem, follow the below steps:
1. Goto Start > Run, type cmd and press enter, this will open command prompt.
2. Type the following command on the command prompt replacing X with the drive letter of your pen drive.
CHKDSK X: /F
The above two methods will help you fix the problem.
Note: For all those who are out of luck in fixing the problem with their portable drives, I would suggest you to get your drives checked or replaced by the manufacturer to fix it for you

Trouble:
Sometimes it happens in windows XP that you are not able to open drives on your hard disk. When you double clicking on the drives icons or right click on the drive>>explore in My computer ,the drive does not open.
This problem is generally caused by most of the viruses which infect windows XP system. They block or restrict your access to any of the drives.
But don’t worry this is not a big trouble it can be fixed easily.

Fix:
Normally when a virus infects a windows system which causes a drive opening problem, it automatically creates a file named autorun.inf in the root directory of each drive.
This autorun.inf file is a read only ,hidden and a system file and the folder option is also disabled by the virus. This is deliberately done by the virus in order to protect itself.  autorun.inf initiates all the activities that the virus performs when you try to open any drive.
You have to just delete this file and restart your system to correct this problem.
Follow the set of commands below to show and delete the autorun.inf
1. Open Start>>Run and type cmd and press enter. This will open a command prompt window. On this command prompt window type the following steps.
2. type cd\
3. type attrib -r -h -s autorun.inf
4. type del autorun.inf
5. now type d: and press enter for d: drive partition. Now repeat steps 3 and 4. Similarly repeat step 5 for all your hard disk partition.
Restart your system and your trouble will be fixed.
Update:
If you find the above procedure difficult, the use:  Scan and Remove Suspicious ‘autorun.inf’ with Autorun Eater

Note: For all those who are not able to correct this problem, after following the above procedure can use a tool called Ravmon Virus Killer designed by Muhammad Abdullah, download it from here
