I need help getting clean

While running a periodic Spybot check I found that my computer has been infected. The Spybot results showed 'Hupigon 13' and 'Win32.Agent.pz' problems. Any help would be greatly appreciated. Here is the HijackThis log:

I am sorry to inform you that one or more of the identified infections on your system is a Backdoor Trojan.

Backdoor Trojans are the most dangerous and most widespread type of Trojan. Backdoor Trojans provide the author or "master" of the Trojan with remote "administration" of victim machines. Unlike legitimate remote administration utilities, they install, launch and run invisibly, without the consent or knowledge of the user. Once installed, Backdoor Trojans can be instructed to send, receive, execute and delete files, harvest confidential data from the computer, log activity on the computer and more.

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.

In addition to the Backdoor Trojans that have been identified, your computer is afflicted with multiple other infections. Although we can make an attempt to clean this machine, we cannot guarantee that it will be secure afterwards. Your best and safest course of action is a reformat and reinstallation of the Windows operating system.

If you do decide to attempt cleaning rather than a reformat, do understand that although we may be able to remove all known visible malware, we cannot guarantee that unknown and unseen malware will have been removed, nor will your system be restored to its pre-infection state. We cannot remedy unknown changes the malware may likely have made in order to allow itself access, nor can we repair the damages it may possibly have caused to vital system files.

Please note that even if we should be successful in removing these infections from your system, it is quite possible that the changes made to the system by the malware may impact negatively on your computer during the removal process. In short, your system may never regain its former stability or its full functionality without a reformat.

Should you have any questions, please feel free to ask.
