Sorry modz, problem sorted it was a virus lol
For anyone who might get this problem:
Type "taskmgr.exe /m" in the Run menu and hit enter. The Processes window will popup all greyed out so you can't see the processes. Double click the area where it should be and it will look like it is going full screen.
Press ALT+F4 to close it, go into Run again and type the same info in... It should pop up with just the processes and nothing else on the screen. Delete the dll16 and any other dodgy looking processes. It will say it is unsafe etc etc, but just end it.
Should be ok after that. Run your AV software and it should kill it!
Norton decided to detect the virus after I fixed its damage :s
You can delete this thread if you want admins - sorry people!
