I need removal help please....Trojan.Gen and Trojan.Gen.2

Hi,

I'm running Windows7 Home Premium, 64 bits, and auto protect blocks this Trojan Gen, but it came back two  times yesterday and today.  I think I see the files in quarantine. I"m worried this keeps coming back.

This is a toshiba laptop.

I have an external drive seagate go with photos that I can conect.

 

I would appreciate if someone could help me figure out how to stop this thing from spreading.
