Ok. Please do the following & we will see if we can get it sorted for you.
Download CWShredder from here & run it. Select the fix button & it will get rid of everything related to CoolWebSearch in it's database. Close ALL windows, including IE, before running CWShredder. REBOOT.
To help prevent this from happening again, install the patches for the vulnerabilities that this hijacker exploits by going here for your critical updates.
Close all (browser) windows & rescan with hijackthis. When the scan is finished place a check in the box to the left of the following entries & click 'fix checked' :
O4 - HKLM\..\Run: [RunDLL] rundll32.exe "C:\WINNT\System32\bridge.dll",Load
O16 - DPF: {34805D32-AD89-469E-8503-A5666AEE4333} - http://207.188.7.150/259d6fbd94e630...etzip/RdxIE.cab
Go here for an on-line scan & set it to autoclean for you.
This is just a precaution. Please report back what the scan finds, if anything.
You also need SP4 for W2K. & SP1 for IE6. They are a must.
Reboot after doing this & post another log please.
