Help!! I think I am infected

Hi


When I ran Norton, the scan did not come up.  So i tried using AVG, it told me that I had this:

"C:\WINDOWS\system32\drivers\kbiwkmvuhfmnus.sys";"Hidden driver"

 

I have read a post about kbiwk rootkit as a problem and nothing I do seems to make it go away...

 

Can you please give me some help?

 

Thank you so much
