DHL Email Virus Removal - unable to login even on safe mode

Hi,

I have opened the DHL zip email and my computer is infected. I know there are a number of DHL virus removal threads and have read the Read & Run Me thread to try and run in safe mode to go through the steps but the system won't even allow me to go past the login page. After I trying to enter my password in normal and safe modes, it keeps logging me out automotically and keeps repeating.

Here is what I've done since my computer was infected: I downloaded SuperAntiSpyware, ran a full scan, kept the log and deleted the files found by the scan. The pop ups still came up and computer was still slow so I tried to uninstall and re-install SuperAntiSpyware again. My computer froze and switched it off and back on again and at this point, it won't let me past the login page and keeps logging me out automatically.

I was hoping someone may be able to help me with this.

I'm currently running Windows XP, SP3 (I'm pretty sure). Not sure what other information is required but let me know.

thanks in advance,

NY
