Need help with a Skynet Virus

Hello,

 

My Internet service was suspended and was told by my internet provider it was becuase I had a skynet port 25 virus. I was told to update my anti-virus programs and run a full scan. I ran Norton Internet Security, Spybot, and Malwarebytes abd they all found nothing.

 

I need help on how to remove this virus from my computer and help would be appreciated.
