Infected with "malware.gen-2011114"?

Hello,

 

Wondering if this is really an infection. I have Norton Internet Security 2012 version 19.5.1.2 and just ran a full system scan with results that everything is clean.  However, I also have the program "Advanced System Optimizer 3", version 3.2.648.12989 from Systweak and when I run a scan from the "System Protector", it always comes out with 1 spyware infection called "malware.gen-2011114".  The program says it quarantined it and my PC is now clean but when I run another scan, right after this one, without even being on the web, I still have this spyware infection called "malware.gen-2011114". 

 

The thing is, this program gives me the location of the spyware and it's located in "...nortoninstaller/(0c55c096-0f1d-4f28-aaa2-85ef591126e7)/nis/2454b0ab/17.9.0.12/inststub.exe".

 

Is this really a spyware? Why does Norton ain't able to pick this one up?  Why this supposed spyware in my Norton folder?

 

Thank you!
