Norton Not Scanning - Virus?

Hi,

 

I seem to be having the same prob as a few others, in that my computer from friday, will not run a norton quick scan or full scan and wont close after attemped start.

 

i would be extremly gratful if you could guide me through a fix.

 

I have made a start by running GMER scan (currently scanning) do i post results here?

 

any help would be great,

 

Cheers
