Hi. First of all you need to update hijackthis to version 1.98.2. Run hijackthis & go to *Config\Misc Tools\Check for update on-line*. If the site is down, go here. Remove the old version by deleting the file manually. Unzip the new version into the hijackthis folder.

Open Task Manager & end process on the following:
WinUpdt.exe
cnlhii.exe
WinKA.exe

Delete these manually:
C:\Program Files\WindUpdates-folder
C:\WINNT\system32\cnlhii.exe-file

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':

O1 - Hosts file is located at: C:\WINNT\nsdb\hosts
O1 - Hosts: 81.211.105.69 lender-search.com

Download the Hoster from here. Press "Restore Original Hosts" and press "OK". Exit Program.

Reboot & post another log please. Will not be able to get back until tomorrow, it's bedtime .

OK, I updated HijackThis and removed all the things you said. But I couldnt cancel the three files:

WinUpdt.exe
cnlhii.exe
WinKA.exe

When I tried to cancel them, they just popped right up again in the bottom of the list, so I can't delete them either...

I also downloaded the Hoster and did what you said, as well as rebooting and scanning again, and here is the new log:
