Comp stuck in reboot cycle except in safe mode

[khublai]

A couple weeks ago a room full of drunks were viewing/downloading something on my computer without me there - next day I started getting popups that "your comp is hooped unless you download and buy this now" which I ignored (too busy). Now I have popups for Antivirus Pro which is bogus but I can't find it to remove it and things are getting more serious. Went through several support sites and downloaded several apps to fix it but none worked. Tried to restart and the computer got as far as the login to windows screen then when I clicked the profile it rebooted no matter which profile I tried. My computer came with an image so if push comes to shove I can use it but it will cost me lots of data. Any help would be greatly appreciated - sorry I don't have more details but it is a shared computer and it sees a lot of use without my supervision (which I'm gonna have to do something about). I run XP and my system restore is not working but I do have a valid restore point. I've already backed up my registry with ERUNT and the HijackThis log follows:

One or more of the identified infections is 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? (http://www.dslreports.com/faq/10451)
When Should I Format, How Should I Reinstall (http://www.dslreports.com/faq/10063)

However, if you do not have the resources to reinstall your computer and would like me to attempt to clean it, I will be happy to do so.
Should you have any questions, please feel free to ask.

Please let us know what you have decided to do in your next post.
