I have been getting crc errors when trying to install games and extract zip folders. My pc has also been doing some strange things, like taskbar changing from blue to grey and the sound not working.

Looks normal, though I'm not a `trained expert` in HJT logs.
Why do you assume infection? Have you run a ChkDsk, an HD diagnostic from your HD manufacturer, a memory test ? Admittedly memory problems usually result in blue screens but worth doing anyway. Ensure all your devices are using the latest drivers. Do a System File Check too.

Run ChkDsk; http://support.microsoft.com/kb/315265
Run SFC; http://www.updatexp.com/scannow-sfc.html

Manufacturers HD diagnostics;

Taskbar colour change - go into Control Panel/Desktop and ensure Windows XP theme is selected;http://www.helpwithpcs.com/tipsandtricks/changing-theme-win-xp.htm

If it is selected and you still have the plain-looking Classic appearance - ensure the Themes service is started and set to Automatic. Go to Start menu/run, type Services.msc, press return, scroll down the list to Themes and check the aforementioned settings.

I have run memtest 86 overnight. I have tried dropping my O/C back to standard. Whatever this is it disables my anti virus when it changes the taskbar colour. I have replaced my hdd with a new one still get the problem. I am doing a complete virus scan on panda active online atm.

Does it stop any other services when this happens? System Restore no good? Any enlightening entries in the Event log?
