You got bugs :). You may want to create a new folder for hijackthis as it will dump it's backups throughout spybot's folder.
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':

C:\Program Files\Common Files\Presentia-folder
c:\program files\partypoker-folder
C:\WINDOWS\System32\gmfpaq.exe-file
c:\WINDOWS\System32\zzb.exe-file

Download & instal Adaware from here

In settings under 'scanning,' have it set to
'scan within archives,'
'scan active processes,'
'scan registry,'
'deepscan registry'
'scan my IE Favourites for banned URL's,'
'scan my host's file.'
In 'tweaks' under 'scanning engine' set it to 'unload recognised processes during scanning.'
Also in 'tweaks' under 'cleaning engine' set it to 'Always try to unload Modules before deletion' & 'let Windows remove files in use at next reboot.'
Select 'activate in-depth scan' before starting scan.
When the scan is finished select 'next.'
Remove what it finds by placing a check in the box to the left of the object. Reboot
Download & instal Spybot S&D from here. Update it before scanning.
After the scan is complete, have spybot fix everything marked RED.
On the page that first opens when you start Spybot there is an option to immunise, you should do this. In the immunise section there is also a link to download Spywareblaster. This program will prevent the install of bad activex controls that it has knowledge of. Download that & you can keep it updated by selecting the same link that you use to download it. Reboot
Post a new log after doing the above.
