Open IE in "No Addon" mode (you can do this by opening the start menu and typing Internet into the search box, you should see a shortcut for Internet Explorer (No Addons).  Does this still happen? IF not an addon is to blame for your problem.

Once IE is open, click tools, manage addons, and disable any addons you think might be the problem (you can't break anything by doing this, as you can always re-enable an addon if you think you need it at a later time).  

This will likely fix the problem you are having, but the software causing this is still installed and should be removed, once it is identified.

In addition to the above, check the settings in Norton 360 carefully. Try disabling for a few minutes and see if the problem goes away. Norton 360 likes to protect you by denying connectivity and I recommend Norton Internet Security as a better choice for individuals.

Also look in your HOSTS file and make sure all the entries in the file are comments.

c:\windows\system32\drivers\etc\hosts

To what site are you being redirected?

I would try rogue killer. http://www.geekstogo.com/forum/files/file/413-roguekiller/

I get taken to this website:
http://63.209.69.107/search/web/happens+water+vacume/6678_a10/46573-178852-1351-27681/v5

And I've disabled all add-ons, my main browser is Firefox.

@needafix - You havent't answered the question about the HOSTS file. However, your system seems to be very badly infested with malware. If the suggestions to elminate malware are not working, then you should back up your system carefully, delete all partitions (to get rid of rootkit malware), format a new partition and reinstall Windows from the Recovery DVD or from the Windows 7 DVD. ....

needafix--That site to which you are being redirected
http://63.209.69.107/search/web/happens+water+vacume/6678_a10/46573-178852-1351-27681/v5
has problems.  It also has misspellings.  
I suspect you still have malware on the PC.  
Have you tried the suggestions in http:#a38785342  ?

It appears to me that all the entries are in comments, in the Host file. Also, that is not the only website it sends me to, its just the most common one.  
Here are some other websites it sends me to:

I did a search on bubbles just to get an example and I was able to grab this redirect before it changed:
