I finally was able to go through your last HJT log. There are some items you can fix, not necessarily bad but more clutter than anything. Run HJT again and place checkmarks next to the following if still showing;

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://www.dell.co.uk/myway
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://www.google.co.uk/
R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://www.dell.co.uk/myway
R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page = http://www.dell.co.uk/myway
R1 - HKCU\Software\Microsoft\Internet Connection Wizard,ShellNext = http://www.dell.co.uk/myway

Are you still using the Tiscali browser? If not then place a checkmark next to this one;
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Window Title = Tiscali 10.0

O2 - BHO: Malicious Scripts Scanner - {55EA1964-F5E4-4D6A-B9B2-125B37655FCB} - C:\Documents and Settings\All Users\Application Data\Prevx\pxbho.dll
O3 - Toolbar: (no name) - {BA52B914-B692-46c4-B683-905236F6F655} - (no file)

These O4 items noted below are all starting when Windows starts and are unnecessary to the running of the computer. All can be run manually if you want to use them.

O4 - HKLM\..\Run: [RUNDLL32.EXE C:\WINDOWS\system32\NvCpl.dll,NvStartup>>> System Tray icon used to change display settings, change the clock rate and memory speed for nVidia based graphics cards. This is unnecessary since you can easily configure these settings the way you want them in the Display Properties and not have to mess with them again.

O4 - HKLM\..\Run: [DVDLauncher] "C:\Program Files\CyberLink\PowerDVD\DVDLauncher.exe">>> A process belonging to the Cyberlink PowerCinema video viewing software which allows you to play DVDs upon insertion. Non-essential process - and is installed for ease of use

O4 - HKLM\..\Run: [CTSysVol] C:\Program Files\Creative\SBAudigy2\Surround Mixer\CTSysVol.exe>>> Creative sound card volume controls

O4 - HKLM\..\Run: [CTDVDDet] C:\Program Files\Creative\SBAudigy2\DVDAudio\CTDVDDet.EXE>>>Auto-detect and play a DVD when using a Creative Soundblaster Audigy2 soundcard. Uses about 2.2 MB of memory. Disable it by heading to the MediaSource DVD Audio Player, selecting Tools, then uncheck the Auto Start box. It should not start up automatically again

O4 - HKLM\..\Run: [CTHelper] CTHELPER.EXE>>>CTHELPER is a background task that is a plug-in manager for Creative drivers. The theory is that 3rd party manufacturers can use the CTHELPER plug-in interface to produce drivers, add-on features, and fixes that will integrate with a tighter fit with Creative’s sound drivers and utilities. Given its purpose CTHELPER would normally be classified as a "leave alone" background task. It also allows Creative speaker setup to be synchronized with Windows Control Panel speaker setting. Without it running that check box in Creative speaker setting is not functional (settings are not in sync). Unfortunately there are often problems with CTHELPER, most notably that it can use 100% of CPU time so it's best left disabled unless you need it

O4 - HKLM\..\Run: [UpdReg] C:\WINDOWS\UpdReg.EXE>>>Reminder to register Creative Labs SoundBlaster Live! Cards

O4 - HKLM\..\Run: [QuickTime Task] "C:\Program Files\QuickTime\qttask.exe" -atboottime>>>System Tray access to Apple's "Quick Time" viewer

O4 - HKLM\..\Run: [TkBellExe] "C:\Program Files\Common Files\Real\Update_OB\realsched.exe" -osboot>>>Application Scheduler installed along with RealOne Player. Once installed, it runs independently of RealOne Player. To disable "tkbell.exe" in the new version (1) Start RealOne Player (2) Tools -> Preferences (3) Automatic services in the Categories pane (4) Uncheck all options and then OK

O4 - HKLM\..\Run: [nwiz] nwiz.exe /install>>>Associated with the newer versions of nVidia graphics cards drivers. Allows you to immensely improve desktop layouts by setting preferences and optimizations. However, this isn't necessary for the operation of your system

O4 - HKLM\..\Run: [Logitech Utility] Logi_MwX.Exe>>>Logitech Mouseware driver. Needed to support some additional functionality of Logitech mice/trackballs such as "SmartMove". If you disable it and find you don't need it leave it disabled

O4 - HKLM\..\Run: [NvMediaCenter] RUNDLL32.EXE C:\WINDOWS\system32\NvMcTray.dll,NvTaskbarInit>>>System Tray icon used to manage settings for nVidia based graphics cards. May be required for some 3D applications to recognize your card correctly - such as the game "Everquest". Otherwise, settings can be changed manually via Display Properties

O4 - HKCU\..\Run: [SpybotSD TeaTimer] C:\Program Files\Spybot - Search & Destroy\TeaTimer.exe>>>TeaTimer.exe monitors certain changes to the registry and notifies when browser plugins and activeX controls get installed, allowing you to block/reverse this. Not required. Turn it off.

O4 - HKCU\..\Run: [msnmsgr] "C:\Program Files\MSN Messenger\msnmsgr.exe" /background>>>Available via Start -> Programs. Go to MS Messenger > Tools > Options > Preferences and uncheck "Run this program when Windows starts"



I would recommend using a program like Mike Lin's Startup Control Panel to turn off the above noted items. Very easy to use as it is only one step and it is FREE.
