infected with W32/Blaster.worm & Internet Security dosn't let my exes work

First of all I have Windows Vista home Premium and a 3 years old Laptop vom Sony Vaio.
Yesterday evening i was in the internet, suddenly a window appeared with the name "Internet Security" wich told me that some of the files or data on my Computer were infected. ALso some alterts poped up like:"Malicious Program has been detected. Click here to detect your COmputer." Internet Security also scanned my PC and told me that I have 80 infected files or data. When I tried to get back in the Internet via "Firefox" it told me that "firefox.exe can not start. File firefox.exe is infected by W32/Blaster.worm. Please activate Security Protection to protect your computer." So I used the Computer from my roommade and I googled the worm. Now I know, that "Internet security" is a fake System who just tell lies! Great!
So I googled again and started with your description "Remove Security Protection (Uninstall Guide)". Everything worked until I got to the point where I should install the TDSSKiller. The TDSSKiller wasn't able to clean the infection. SO I went to the next step: "If TDSSKiller was unable to remove the TDSS infection, even though it detected it but was unable to cure it, then you should follow the steps here to request assistance from one of our malware removal experts:Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help".
I did everything step by step, first made a backup on two dvd's. Then "cleaned" my Computer, created a new account, I enabled the firewall(which actually was already enabled!?)and disabled my CD Emulation Software(whatever that is... Sorry, I really am no Computergenius...). Then the first mistake appeared. I tried to do the DDS and at first it was working, but there were no two windows popping up titled: "DDS.txt" and "Attach.txt" as in the discription. There was only this black window appearing with the white letters, it closed really fast and that was it. So I just went on to the next step. I created a Gmer log. The scan took really long but I think it worked.
Well, and here I am. The attached file is the stuff I got from the Gmer log. I hope it tells You something usefull.
I think that's about everything that happened to me in the last 18hours...
I hope you can help me soon, I would realy like to work with my laptop again...

Plug the flashdrive into the infected PC.
