I've found the solution to my problem on another Forum. Here it is
Run HijackThis and place checks beside each of the following:
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://www.newgenlook.info/ad/ad0202/
or whatever web page you might have there like servicegoods.com
If you, or an administrator, set these restrictions on purpose (i.e., if you used Spybot's Home Page and Option Lock down features in the Immunize section, or you used a similar program to place them, leave them alone. Otherwise check them also.
O6 - HKCU\Software\Policies\Microsoft\Internet Explorer\Restrictions present
O6 - HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel present
After you check these items, close all browsers and windows, except for HijackThis, then click on the Fix Checked button on HijackThis.
Now click on the Config.. button on the bottom right of HijackThis, click on the Misc Tools button up at the top right, click on Delete a file on reboot under System Tools. Select this file in bold:
If you do not see the file you may have to configure Windows to show hidden files and folders:
Reconfigure Windows XP to show hidden files:
Click Start. Open My Computer.
Select the Tools menu and click Folder Options. Select the View Tab.
Under the Hidden files and folders heading select "Show hidden files and folders".
Uncheck the "Hide protected operating system files (recommended)" option.
Uncheck the "Hide file extensions for known file types" option.
Click Yes to confirm. Click OK.
After you select the file close HijackThis and reboot your computer.
Immediatly after run ad-aware, spy sweeper and Microsft Anti-Spyware to get rid of all the spyware program this program might have installed. Use Microsoft anti-spyware to be sure that your homepage is not pointing to any unwanted site.
