Tell us more about your situation.
Obviously you have more than one computer, so you can connect to some sites for downloading tools - right?

Here is my basic 1-2-3 for this:

For Hijacking/re-directs, you might want to start with TDSSKILLER found here:
http://support.kaspersky.com/downloads/utils/tdsskiller.zip

* Download the file TDSSKiller.zip and extract it into a folder on the infected (or potentially infected) PC.
* Execute the file TDSSKiller.exe.
* Wait for the scan and disinfection process to be over. You do not have to reboot the PC after the disinfection is over.

If the tool finds a hidden service it will prompt you to type "delete",  you can also just hit "Enter" without typing in and the scan will continue...
The user can then post the log to be analyzed.

Let us know the results and we can take the next steps.
***********************

Download, install, and run
CCleaner (www.ccleaner.com)
Doing this will clean out all of the Temp/Junk files from your browser.
************

Download, install, and run
Malwarebytes (MBAM) (http://www.malwarebytes.org/mbam.php)
When downloading, save to your "Desktop" and use the "Save As" function (Internet Explorer) to rename the file.
The instructions are included right in that link.

If you need to manually download the latest update, use this link:
http://data.mbamupdates.com/tools/mbam-rules.exe

When finished with MBAM, post the log that is generated and let us look at it for you.

IF NEEDED, we may ask you do download ComboFix (using the same "Save As" process).

OK - great.
Please note the "Save As" instructions.
Some malware can recognize the MBAM executable when it lands on your computer and disable before you even get started.

I got Windows XP Prof  SP3.
I have just tried to go on internet under  'Safe Mode with Networking' and it was working.
So I restart my PC and tried to check on Normal Mode but again IE not working in Normal Mode.
Hmm strange..

Not really, it sounds like it's being caused by an add-on.

In normal mode start IE without add-ons. Start>Run> then enter iexplore -extoff

If it works that way then that's the problem.

I am about to call it a night so I will suggest  the last thing that comes to mind. If it doesn't work hopefully someone else will come along to assist you. If not, I will be back early AM EST.

It sounds like your anti virus or other security software might be causing this. I would try un-installing them temporarily to test.

<<I had Malware.exe from long back on my infected PC, I have installed that and ran a quick scan first, >>

I am not sure what you meant by this comment - but if you haven't downloaded a new version of MBAM - with the separate 'update' file - you need to do that.

I believe this is a very old variant of malware and the current set of MBAM should remove all traces and effects.

If you are still having connectivity problems after running the new version - reboot to Safe Mode with Networking and try to connect here:

Just thought of this also - "HOSTS" file may be corrupted.
If you can get to this link, try to download and install the modified HOSTS file.

You can also download it to your good computer and computer the zip file over to the infected one.
