I have been having problems with my constant redirects or new browser windows opening unexpectedly. I am running Windows 7 and use Firefox as my browser; I tried using Internet Explorer and had the same problem. My antivirus software is Eset's Nod32 and I have used SuperAntiSpyware.
While trying to figure out the problem, I was in safe mode and ran Microsoft Windows Malicious Software Removal Kit and all it has found is Backdoor:Win32/IRCBOT.bt and states that it has partially removed it. The instructions say to run a full scan using an antivirus program. I do and my program finds nothing. By the way the redirecting etc. happens in safe mode also.

What should I do now?

Hello and welcome. A backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook
