No Internet Connection

I have a desktop which is connected to a SOHO and it is running Windows XP Pro.
It appears that I have picked up a nasty virus which is redirecting my browser and now is preventing me from connecting to the Internet. I am attaching a HijackThis Log. Any assistance would be greatly appreciated.

Welcome to Lockergnome.

Please print the below instructions or copy them to Notepad. Make sure to work through the fixes in the order mentioned below. If there's anything that you don't understand, ask your question(s) before proceeding with the fixes.

Before you do anything else, create a folder for HijackThis and put it in a permanent folder (like C:\HJT) instead of the Temp folder. This is required because HijackThis will create backups and we don't want them to be deleted.

Download ATF Cleaner at http://www.atribune.org/ccount/click.php?id=1
Double-click ATF-Cleaner.exe to run the program. Under Main choose Select All
Click the Empty Selected button.

If you use the Firefox browser click Firefox at the top and choose Select All
Click the Empty Selected button.
NOTE: If you would like to keep your saved passwords, please click No at the prompt.

If you use the Opera browser click 'Opera' at the top and choose 'Select All'
Click the Empty Selected button.
NOTE: If you would like to keep your saved passwords, please click No at the prompt.

Click Exit on the Main menu to close the program.

Download Malwarebytes ' Anti-Malware at http://www.besttechie.net/tools/mbam-setup.exe or http://www.majorgeeks.com/Malwarebytes_Anti-Malware_d5756.html Double-click on mbam-setup.exe to install the application.

* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform Full Scan, then click Scan.
* The scan may take some time to finish, so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to restart (see Extra Note below).
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy & paste the entire report into your next reply.

Extra Note:
If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately.

Run a scan in HijackThis. Check each of the following if they still exist and hit 'Fix Checked' after you checked the last one:
