You have
Cssdll32.dll Trojan/Backdoor on your computer, that´s probably why you always gets redirected.
There are also remnants from Norton, I´ll therefore suggest you run their own Removal Tool (SymNRT) save it to your Desktop.

Once downloaded please close ALL open browsers, also save any work because this may require a restart.
Go to your desktop and double click on the removal tool and then click Setup.
Once open Click Next
Accept the license agreement and click Next
Type in the letters/numbers that you see into the text box then click Next.
Then click Next and the tool will start running.
Once finished restart the PC and run the tool again to ensure everything has been removed.
Delete Nortonremoval tool from your Desktop.
Reboot.
Please download Combofix from:
http://subs.geekstogo.com/ComboFix.exe
And save to the desktop.
Close all other browser windows.
Double-click on the combofix icon found on your desktop.
Please note, that once you start combofix you should not click anywhere on the combofix window as it can cause the program to stall. In fact, when combofix is running, do not touch your computer at all and just take a break as it may take a while for it to complete.
When finished, it will produce a logfile located at C:\combofix.txt.
Attach the contents of that log in your next reply
